[ Upstream commit 86279456a4d47782398d3cb8193f78f672e36cac ]

[ Upstream commit f4443293d741d1776b86ed1dd8c4e4285d0775fc ]
When wlc_phy_txpwr_srom_read_lcnphy fails in wlc_phy_attach_lcnphy,
the allocated pi->u.pi_lcnphy is leaked, since struct brcms_phy will be
freed in the caller function.
Fix this by calling wlc_phy_detach_lcnphy in the error handler of
wlc_phy_txpwr_srom_read_lcnphy before returning.

[ Upstream commit c0014f94218ea3a312f6235febea0d626c5f2154 ]
Emit a warning when ->done or ->free are called on an already freed
srb. There is a hidden use-after-free bug in the driver which corrupts
the srb memory pool which originates from the cleanup callbacks.
An extensive search didn't bring any lights on the real problem. The
initial fix was to set both pointers to NULL and try to catch invalid
accesses. But instead the memory corruption was gone and the driver
didn't crash. Since not all calling places check for NULL pointer, add
explicitly default handlers. With this we workaround the memory
corruption and add a debug help.

[ Upstream commit b77d2a0a223bc139ee8904991b2922d215d02636 ]
Some integrated OHCI controller hubs do not expose all ports of the hub
to pins on the SoC. In some cases the unconnected ports generate
spurious over-current events. For example the Broadcom 56060/Ranger 2 SoC
contains a nominally 3 port hub but only the first port is wired.
Default behaviour for ohci-platform driver is to use global over-current
protection mode (AKA "ganged"). This leads to the spurious over-current
events affecting all ports in the hub.
We now alter the default to use per-port over-current protection.
This patch results in the following configuration changes depending
on quirks:
- For quirk OHCI_QUIRK_SUPERIO no changes. These systems remain set up
for ganged power switching and no over-current protection.
- For quirk OHCI_QUIRK_AMD756 or OHCI_QUIRK_HUB_POWER power switching
remains at none, while over-current protection is now guaranteed to be
set to per-port rather than the previous behaviour where it was either
none or global over-current protection depending on the value at
function entry.

[ Upstream commit cb60e9602cce1593eb1e9cdc8ee562815078a354 ]
If dev_pm_opp_attach_genpd() is called multiple times (once for each CPU
sharing the table), then it would result in unwanted behavior like
memory leak, attaching the domain multiple times, etc.
Handle that by checking and returning earlier if the domains are already
attached. Now that dev_pm_opp_detach_genpd() can get called multiple
times as well, we need to protect that too.
Note that the virtual device pointers aren't returned in this case, as
they may become unavailable to some callers during the middle of the
operation.

When mfd_add_devices() fail, pcr->slots should also be freed. However,
the current implementation does not free the member, leading to a memory

[ Upstream commit 110003002291525bb209f47e6dbf121a63249a97 ]
The T820, G31 & G52 GPUs integrated by Amlogic in the respective GXM,
G12A/SM1 & G12B SoCs needs a quirk in the PWR registers at the GPU reset
time.
Since the Amlogic's integration of the GPU cores with the SoC is not
publicly documented we do not know what does these values, but they
permit having a fully functional GPU running with Panfrost.

usb_kill_anchored_urbs()
[ Upstream commit 03fb92a432ea5abe5909bca1455b7e44a9380480 ]
Calls to usb_kill_anchored_urbs() after usb_kill_urb() on multiprocessor
systems create a race condition in which usb_kill_anchored_urbs() deallocates
the URB before the completer callback is called in usb_kill_urb(), resulting
in a use-after-free.
To fix this, add proper lock protection to usb_kill_urb() calls that can
possibly run concurrently with usb_kill_anchored_urbs().

[ Upstream commit 960c7339de27c6d6fec13b54880501c3576bb08d ]
Handle broken union functional descriptors where the master-interface
doesn't exist or where its class is of neither Communication or Data
type (as required by the specification) by falling back to
"combined-interface" probing.
Note that this still allows for handling union descriptors with switched
interfaces.
This specifically makes the Whistler radio scanners TRX series devices
work with the driver without adding further quirks to the device-id
table.

[ Upstream commit cc1a2679865a94b83804822996eed010a50a7c1d ]
Since struct _mic_vring_info and vring are allocated together and follow
vring, if the vring_size() is not four bytes aligned, which will cause
the start address of struct _mic_vring_info is not four byte aligned.
For example, when vring entries is 128, the vring_size() will be 5126
bytes. The _mic_vring_info struct layout in ddr looks like:
0x90002400: 00000000 00390000 EE010000 0000C0FF
Here 0x39 is the avail_idx member, and 0xC0FFEE01 is the magic member.
When EP use ioread32(magic) to reads the magic in RC's share memory, it
will cause kernel panic on ARM64 platform due to the cross-byte io read.
Here read magic in user space use le32toh(vr0->info->magic) will meet
the same issue.
So add round_up(x,4) for vring_size, then the struct _mic_vring_info
will store in this way:
0x90002400: 00000000 00000000 00000039 C0FFEE01
Which will avoid kernel panic when read magic in struct _mic_vring_info.

[ Upstream commit bbe516e976fce538db96bd2b7287df942faa14a3 ]
pm_runtime_get_sync() increments the runtime PM usage counter even
when it returns an error code. Thus a pairing decrement is needed on
the error handling path to keep the counter balanced. For other error
paths after this call, things are the same.
Fix this by adding pm_runtime_put_noidle() after 'err_runtime_disable'
label. But in this case, the error path after pm_runtime_put_sync()
will decrease PM usage counter twice. Thus add an extra
pm_runtime_get_noresume() in this path to balance PM counter.

[ Upstream commit e1c69c4eef61ffe295b747992c6fd849e6cd747d ]
There are few list handling issues while adding and deleting
node in the registered buf list in the driver.
1. list addition - buffer added into the list during buf_init
while not deleted during cleanup.
2. list deletion - In capture streamoff, the list was reinitialized.
As a result, if any node was present in the list, it would
lead to issue while cleaning up that node during buf_cleanup.

[ Upstream commit 8a652a17e3c005dcdae31b6c8fdf14382a29cbbe ]
bFrameIndex and bFormatIndex can be negotiated by the camera during
probing, resulting in the camera choosing a different format than
expected. v4l2 can already accommodate such changes, but the code was
not updating the proper fields.
Without such a change, v4l2 would potentially interpret the payload
incorrectly, causing corrupted output. This was happening on the
Elgato HD60 S+, which currently always renegotiates to format 1.
As an aside, the Elgato firmware is buggy and should not be renegotating,
but it is still a valid thing for the camera to do. Both macOS and Windows
will properly probe and read uncorrupted images from this camera.
With this change, both qv4l2 and chromium can now read uncorrupted video
from the Elgato HD60 S+.

registering the ACPI i2c devs
[ Upstream commit 8058d69905058ec8f467a120b5ec5bb831ea67f3 ]
Commit 21653a4181ff ("i2c: core: Call i2c_acpi_install_space_handler()
before i2c_acpi_register_devices()")'s intention was to only move the
acpi_install_address_space_handler() call to the point before where
the ACPI declared i2c-children of the adapter where instantiated by
i2c_acpi_register_devices().
But i2c_acpi_install_space_handler() had a call to
acpi_walk_dep_device_list() hidden (that is I missed it) at the end
of it, so as an unwanted side-effect now acpi_walk_dep_device_list()
was also being called before i2c_acpi_register_devices().
Move the acpi_walk_dep_device_list() call to the end of
i2c_acpi_register_devices(), so that it is once again called *after*
the i2c_client-s hanging of the adapter have been created.
This fixes the Microsoft Surface Go 2 hanging at boot.
