05165248df media: v4l2-ctrls-api.c: move ctrl->is_new = 1 to the correct line
The patch that fixed string control support somehow got mangled when it was
merged in mainline: the added line ended up in the wrong place.

Fix this.

4d25e97747 media: imx-pxp: Use non-threaded IRQ
There's no need to use threaded IRQs with the PXP, as the interrupt
handler doesn't need to sleep and doesn't perform any time-consuming
operation. Switch to regular IRQ handler.

This fixes lockups of the PXP noticed on i.MX7, where the PXP would stop
generating interrupts after a variable number of frames (from a few
dozens to a few hundreds). The root cause is however unknown.

Various multiplexers in the pipeline are not used with the currently

The datasheet doesn't explicitly require this, but the PXP has been seen

relevant for the data path.

It is unclear, if the PXP on these SoCs is compatible to any of the PXPs
on the existing SoCs and would allow to reuse the already defined
compatibles. The missing compatibles should be brought back when the

When the siano device is plugged in, it may call the following functions
to initialize the device.

smsusb_probe()-->smsusb_init_device()-->smscore_start_device().

When smscore_start_device() gets failed, the function smsusb_term_device()
will be called and smsusb_device_t will be deallocated. Although we use
usb_kill_urb() in smsusb_stop_streaming() to cancel transfer requests
and wait for them to finish, the worker threads that are scheduled by
smsusb_onresponse() may be still running. As a result, the UAF bugs
could happen.

We add cancel_work_sync() in smsusb_stop_streaming() in order that the
worker threads could finish before the smsusb_device_t is deallocated.

5a1a39a8ac media: marvell: change return to goto for proper unwind
The probe function used 'goto out' everywhere, except in one
place where it returned an error. That too should be a 'goto out'.

This fixes a smatch warning:
