Pull mfd fixes from Samuel Ortiz:
"This is the remaining MFD fixes for 3.6, with 5 pending fixes:
- A tps65217 build error fix.
- A lcp_ich regression fix caused by the MFD driver failing to
initialize the watchdog sub device due to ACPI conflicts.
- 2 MAX77693 interrupt handling bug fixes.
- An MFD core fix, adding an IRQ domain argument to the MFD device
addition API in order to prevent silent and potentially harmful
remapping behaviour changes for drivers supporting non-DT
platforms."

Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties. This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern. There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.
Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts. The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.

'struct omap_video_timings' was updated w/ a 'bool interlaced'. Without
a matching update in omap_connector, this field could have undefined
values from the stack, which isn't quite ideal.
Update the fxns to convert omapdss<->drm timings structs, and zero-init
'struct omap_video_timings' when it is declared on stack to avoid issues
like this in the future.

This patch fixes a race condition that results in memory
corruption when using cleancache.
The race exists between the zcache shrinker handler,
shrink_zcache_memory() and cleancache_get_page().
In most cases, the shrinker will both evict a zbpg
from its buddy list and flush it from tmem before a
cleancache_get_page() occurs on that page. A subsequent
cleancache_get_page() will fail in the tmem layer.
In the rare case that two occur together and the
cleancache_get_page() path gets through the tmem
layer before the shrinker path can flush tmem,
zbud_decompress() does a check to see if the zbpg is a
"zombie", i.e. not on a buddy list, which means the shrinker
is in the process of reclaiming it. If the zbpg is a zombie,
zbud_decompress() returns -EINVAL.
However, this return code is being ignored by the caller,
zcache_pampd_get_data_and_free(), which results in the
caller of cleancache_get_page() thinking that the page has
been properly retrieved when it has not.
This patch modifies zcache_pampd_get_data_and_free() to
convey the failure up the stack so that the caller of
cleancache_get_page() knows the page retrieval failed.
This needs to be applied to stable trees as well.
zcache-main.c was named zcache.c before v3.1, so
I'm not sure how you want to handle trees earlier
than that.

Hi,
This patch fixes a bug with driver failing to negotiate a connection.
The bug was traced to commit
203e4615ee9d9fa8d3506b9d0ef30095e4d5bc90
staging: vt6656: removed custom definitions of Ethernet packet types
In that patch, definitions in include/linux/if_ether.h replaced ones
in tether.h which had both big and little endian definitions.
include/linux/if_ether.h only refers to big endian values, cpu_to_be16
should be used for the correct endian architectures.

IIO fixes for v3.6-rc1 set 2
A few simple fixes.
1)Fix up some possible divide by zero issues in various drivers.
2)Prevent a memory leak in an error path in lis3l02dq
3)Make sure the PTR_ERR call in at91_adc matches the
check for IS_ERR just above it rather than using a different

The element of `das08_boards[]` for the 'das08jr-16-ao' board has the
`ai_encoding` member set to `das08_encode12`. It should be set to
`das08_encode16` same as the 'das08jr/16' board. After all, this board
has 16-bit AI resolution.
The description of the A/D LSB register at offset 0 seems incorrect in
the user manual "cio-das08jr-16-ao.pdf" as it implies that the AI
resolution is only 12 bits. The diagrams of the A/D LSB and MSB
registers show 15 data bits and a sign bit, which matches what the
software expects for the `das08_encode16` AI encoding method.

When attaching a PCI device manually via the comedi driver `attach` hook
(`das08_attach()`) (called by the comedi core for the `COMEDI_DEVCONFIG`
ioctl), its reference count is incremented in the `for_each_pci_dev`
loop (in `das08_find_pci()`). It is decremented when the `detach` hook
(`das08_detach()`) is called to detach the device. However, when the
PCI device is attached automatically via the `attach_pci` hook
(`das08_attach_pci()`, called at probe time via
`comedi_pci_auto_config()`) it's reference count is not incremented so
there will be an unmatched decrement when detaching the device.
Increment the PCI device reference count in `das08_attach_pci()` to
correct the mismatch.
Once support for manual configuration has been removed from this driver,
the calls to `pci_dev_get()` and `pci_dev_put()` can be removed.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-linus
IIO fixes for v3.6-rc1
These mostly consist of fixes from Lars-Peter Clausen that were
the first part of a large series reworking the drivers concerned.
Turns out these drivers had quite a wealth of minor bugs.
Also here are some build warning fixes for lm3533-als and
adjd_s111 (both new drives in this cycle).
Final elements are a a div factor overflow and a warning
related fix in a couple of Analog Devices drivers.
All in all nothing major, but a worthwhile bunch of short
fixes.

The values reported by the AD7780 are unsigned with a binary offset:
0x000000 is negative fullscale
0x800000 is zeroscale
0xffffff is positive fullscale
So mark the channel in the channel spec as unsigned rather than signed.

The temperature channel reports values in degree Kelvin with sensitivity of 5630
codes per degree. If the chip is configured in bipolar mode there is an
additional binary offset of 0x800000 and the sensitivity is divided by two.
Currently the driver does the mapping from the raw value to degree Celsius when
doing a manual conversion. This has several disadvantages, the major one being
that it does not work for buffered mode, also by doing the division by the
sensitivity in the driver the precession of the reported value is needlessly
reduced.
Furthermore the current calculation only works in bipolar mode and the current
scale is of by a factor of 1000.
This patch modifies the driver to report correct offset and scale values in
both unipolar and bipolar mode and to report the raw temperature value
for manual conversions.

In bipolar mode there is a a binary offset of 2**(N-1) (with N being the number
of bits) on the reported value. Currently this value is subtracted when doing a
manual read. While this works for manual channel readings it does not work for
buffered mode. So report the offset in the channels offset property, which will
work in both modes.

passed to ioremp().
Set the dev->iobase to a dummy non-zero value so that the "detach"
can use it as a flag to know that comedi_pci_disable() needs to
be called.

As mentioned by Ian Abbott, this driver originally checked
the pci_dev subsystem_device in order to make sure that the
pci_dev was compatible with this driver. The cleanup of the
"find pci device" code removed this check. Add it back.

As mentioned by Ian Abbott, the comedi pci drivers that try to
locate an unused pci device with the pci_is_enabled() test
might actually skip over a perfectly good unused device. This
test is also not consistent with the other comedi pci drivers.
Remove the test from all the comedi pci drivers.

Pull OLPC platform updates from Andres Salomon:
"These move the OLPC Embedded Controller driver out of
arch/x86/platform and into drivers/platform/olpc.
OLPC machines are now ARM-based (which means lots of x86 and ARM
changes), but are typically pretty self-contained.. so it makes more
sense to go through a separate OLPC tree after getting the appropriate
review/ACKs."
* 'for-linus-3.6' of git://dev.laptop.org/users/dilinger/linux-olpc:
x86: OLPC: move s/r-related EC cmds to EC driver
Platform: OLPC: move global variables into priv struct
Platform: OLPC: move debugfs support from x86 EC driver
x86: OLPC: switch over to using new EC driver on x86
Platform: OLPC: add a suspended flag to the EC driver
Platform: OLPC: turn EC driver into a platform_driver
Platform: OLPC: allow EC cmd to be overridden, and create a workqueue to call it
drivers: OLPC: update various drivers to include olpc-ec.h
Platform: OLPC: add a stub to drivers/platform/ for the OLPC EC driver

Pull second vfs pile from Al Viro:
"The stuff in there: fsfreeze deadlock fixes by Jan (essentially, the
deadlock reproduced by xfstests 068), symlink and hardlink restriction
patches, plus assorted cleanups and fixes.
Note that another fsfreeze deadlock (emergency thaw one) is *not*
dealt with - the series by Fernando conflicts a lot with Jan's, breaks
userland ABI (FIFREEZE semantics gets changed) and trades the deadlock
for massive vfsmount leak; this is going to be handled next cycle.
There probably will be another pull request, but that stuff won't be
in it."
Fix up trivial conflicts due to unrelated changes next to each other in
drivers/{staging/gdm72xx/usb_boot.c, usb/gadget/storage_common.c}
