Sakari Ailus 7a3c10f3d4 media: v4l: ioctl: Fix memory leak in video_usercopy
commit fb18802a338b36f675a388fc03d2aa504a0d0899 upstream.

When an IOCTL with argument size larger than 128 that also used array
arguments were handled, two memory allocations were made but alas, only
the latter one of them was released. This happened because there was only
a single local variable to hold such a temporary allocation.

Fix this by adding separate variables to hold the pointers to the
temporary allocations.

commit 9dec0f48a75e0dadca498002d25ef4e143e60194 upstream.

prescaler larger than 8 would mean the carrier is at most 152Hz,

commit 6532923237b427ed30cc7b4486f6f1ccdee3c647 upstream.

After the first IR message, interrupts are no longer received. In addition,
the code generates a timeout IR message of 10ms but sets the timeout value
to 100ms, so no timeout was ever generated.

James Reynolds 2204bc0bdf media: mceusb: Fix potential out-of-bounds shift
commit 1b43bad31fb0e00f45baf5b05bd21eb8d8ce7f58 upstream.

When processing a MCE_RSP_GETPORTSTATUS command, the bit index to set in
ir->txports_cabled comes from response data, and isn't validated.

As ir->txports_cabled is a u8, nothing should be done if the bit index
is greater than 7.

Laurent Pinchart 467b54dd6d media: uvcvideo: Accept invalid bFormatIndex and bFrameIndex values
[ Upstream commit dc9455ffae02d7b7fb51ba1e007fffcb9dc5d890 ]

The Renkforce RF AC4K 300 Action Cam 4K reports invalid bFormatIndex and
bFrameIndex values when negotiating the video probe and commit controls.
The UVC descriptors report a single supported format and frame size,
with bFormatIndex and bFrameIndex both equal to 2, but the video probe
and commit controls report bFormatIndex and bFrameIndex set to 1.

The device otherwise operates correctly, but the driver rejects the
values and fails the format try operation. Fix it by ignoring the
invalid indices, and assuming that the format and frame requested by the
driver are accepted by the device.

[ Upstream commit dc1eb7c9c290cba52937c9a224b22a400bb0ffd7 ]

The driver currently reports a single supported value for
V4L2_CID_PIXEL_RATE and initializes the control's minimum value to 0,
which is very risky, as userspace might accidentally use it as divider
when calculating the time duration of a line.

Fix this by using as minimum the only supported value when registering
the control.

As reported on:
	https://lore.kernel.org/linux-media/20190627222020.45909-1-willemdebruijn.kernel@gmail.com/

if gp8psk_usb_in_op() returns an error, the status var is not
initialized. Yet, this var is used later on, in order to
identify:
	- if the device was already started;
	- if firmware has loaded;
	- if the LNBf was powered on.

Using status = 0 seems to ensure that everything will be
properly powered up.

So, instead of the proposed solution, let's just set
status = 0.

commit e297ddf296de35037fa97f4302782def196d350a upstream.

If the call to spi_register_master() fails on probe of the NetUP
Universal DVB driver, the spi_master struct is erroneously not freed.

Likewise, if spi_new_device() fails, the spi_controller struct is
not unregistered.  Plug the leaks.

While at it, fix an ordering issue in netup_spi_release() wherein
spi_unregister_master() is called after fiddling with the IRQ control
register.  The correct order is to call spi_unregister_master() *before*
this teardown step because bus accesses may still be ongoing until that
function returns.

commit 3f56df4c8ffeb120ed41906d3aae71799b7e726a upstream.

If a user holds a button down on a remote, then no ir idle interrupt will
be generated until the user releases the button, depending on how quickly
the remote repeats. No IR is processed until that point, which means that
holding down a button may not do anything.

This also resolves an issue on a Cubieboard 1 where the IR receiver is
picking up ambient infrared as IR and spews out endless
"rc rc0: IR event FIFO is full!" messages unless you choose to live in
the dark.

commit e469d0b09a19496e1972a20974bbf55b728151eb upstream.

The gspca driver leaks memory when a probe fails.  gspca_dev_probe2()
calls v4l2_device_register(), which takes a reference to the
underlying device node (in this case, a USB interface).  But the
failure pathway neglects to call v4l2_device_unregister(), the routine
responsible for dropping this reference.  Consequently the memory for
the USB interface and its device never gets released.

This patch adds the missing function call.

commit 93df48d37c3f03886d84831992926333e7810640 upstream.

uvc_ctrl_add_info() calls uvc_ctrl_get_flags() which will override
the fixed-up flags set by uvc_ctrl_fixup_xu_info().

uvc_ctrl_init_xu_ctrl() already calls uvc_ctrl_get_flags() before
calling uvc_ctrl_add_info(), so the uvc_ctrl_get_flags() call in
uvc_ctrl_add_info() is not necessary for xu ctrls.

This commit moves the uvc_ctrl_get_flags() call for normal controls
from uvc_ctrl_add_info() to uvc_ctrl_init_ctrl(), so that we no longer
call uvc_ctrl_get_flags() twice for xu controls and so that we no longer
override the fixed-up flags set by uvc_ctrl_fixup_xu_info().

This fixes the xu motor controls not working properly on a Logitech
046d:08cc, and presumably also on the other Logitech models which have
a quirk for this in the uvc_ctrl_fixup_xu_info() function.

[ 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.

Vikash Garodia 9309bf7f0d media: venus: fixes for list corruption
[ 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.

Mauro Carvalho Chehab 4dc3e278f8 media: saa7134: avoid a shift overflow
[ Upstream commit 15a36aae1ec1c1f17149b6113b92631791830740 ]

As reported by smatch:
	drivers/media/pci/saa7134//saa7134-tvaudio.c:686 saa_dsp_writel() warn: should 'reg << 2' be a 64 bit type?

On a 64-bits Kernel, the shift might be bigger than 32 bits.

In real, this should never happen, but let's shut up the warning.

Adam Goode b00692a3bd media: uvcvideo: Ensure all probed info is returned to v4l2
[ 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+.

[ Upstream commit 7b817585b730665126b45df5508dd69526448bc8 ]

In bttv_probe if some functions such as pci_enable_device,
pci_set_dma_mask and request_mem_region fails the allocated
 memory for btv should be released.
