commit f4000b58b64344871d7b27c05e73932f137cfef6 upstream.
USB control and interrupt message timeouts are specified in milliseconds
and should specifically not vary with CONFIG_HZ.
Fixes: 705ececd1c60 ("Staging: add line6 usb driver")

Remove Initialization from POD HD500X because it's not needed.
Every time the device is connected dmesg gives the following output:
"receive length failed (error -11)".
To solve this problem, another flags is introduced
(LINE6_CAP_CONTROL_INFO) and it is only used for PODX3 in: sysfs
entries, call podhd_startup_finalize(pod) and disconnection.
With this patch the error disappear.

Userspace apps have to claim USB interfaces before using endpoints in
them (drivers/usb/core/devio.c:checkintf()). It's a lock mechanism so
that two "drivers" don't steal data from each other. Kernel drivers don't
have to claim interfaces to work - but they should, to lock out userspace.
While there, fix line6_properties struct to match checkpatch.pl.

We must do it this way, because e.g. POD X3 won't play any sound unless
the host listens on the bulk EP, so we cannot export it only via libusb.
The driver currently doesn't use the bulk EP messages in other way,
in future it could e.g. sense/modify volume(s).

Not all PODs use MIDI via USB data interface, thus allow avoiding
that code and instead using direct processing.

POD X3 can initialize similarly to older PODs, but it doesn't have the MIDI
interface. Instead, configuration is done via proprietary bulk EP messages.

E.g. POD X3 seems to require playback data to be sent to it to generate
capture data. Otherwise the device stalls and doesn't send any more capture
data until it's reset.

This has two parts:
* intervals_per_second setup
(high speed needs 8000, instead of 1000)
* iso_buffers setup (count of iso buffers depends on
USB speed, 2 is not enough for high speed)

The address cannot be negative so make it unsigned. Also, an unsigned
int is always sufficient for the length, so no need to overdo it with a
size_t. Finally, add in range checks to see if the values passed in
actually fit where they are used.

Provide a unique name for each driver instead of using "line6usb" for
all of them. This will allow for different configurations based on the

line6_start_timer passes an unsigned int as argument to be used in mod_timer
which is then used by mod_timer as unsigned long, this just fixes up the
argument type. This change helps make static code checkers happy.

Just reformatting the comments and typos fixed, no functional
changes. Particularly,
- avoid the kerneldoc marker "/**",
- reduce multiple comment lines into single lines,
- corrected wrongly referred function names

Instead of allocating the private data individually in each driver's
probe at first, let snd_card_new() allocate the data that is called in
line6_probe(). This simplifies the primary probe functions.

The interface argument is used just for retrieving the assigned
device, which can be already found in line6->ifcdev. Drop them from
the callbacks. Also, pass the usb id to private_init so that the
driver can deal with it there. This is a preliminary work for the
further cleanup to move the whole allocation into driver.c.

Split to each individual driver for POD, PODHD, TonePort and Variax
with a core LINE6 helper module. The new modules follow the standard
ALSA naming rule with snd prefix: snd-usb-pod, snd-usb-podhd,
snd-usb-toneport and snd-usb-variax, together with the corresponding
CONFIG_SND_USB_* Kconfig items.

Promote line6 driver from staging to sound/usb/line6 directory, and
maintain through sound subsystem tree.
This commit just moves the code and adapts Makefile / Kconfig.
