Use refcount_t to manage the refcount to the memory type specific buffer
videobuf2 buffer implementations. refcount_t is better suitable for the
purpose than atomic_t.

The VIDIOC_G_EDID implementation in vivid didn't take edid->start_block into account when
copying the EDID data.
Make sure that the internal EDID is updated with the correct CEC physical address. Currently
the returned EDID is updated, but that will only work well if edid->start_block is 0.

The check for ret being non-zero is false as ret is always

The extra pairs of parentheses are not needed and cause clang

The symptom is continuous log "mtk-jpeg 18004000.jpegdec: Context is NULL"
in kernel log. It is because the error handling in irq doesn't clear
interrupt.
The calling flow like as below when issue happen
mtk_jpeg_device_run()
mtk_jpeg_job_abort()
v4l2_m2m_job_finish() -> m2m_dev->curr_ctx = NULL;
mtk_jpeg_dec_irq()
v4l2_m2m_get_curr_priv()
-> m2m_dev->curr_ctx == NULL
-> return NULL
log "Context is NULL"
There is race condition between job_abort() and irq. In order to simplify
code, don't want to add extra flag to maintain state, empty job_abort() and
clear interrupt before v4l2_m2m_get_curr_priv() in irq.

Make sure to check the number of endpoints to avoid accessing memory
beyond the endpoint array should a device lack the expected endpoints.
Note that, as far as I can tell, the gspca framework has already made
sure there is at least one endpoint in the current alternate setting so
there should be no risk for a NULL-pointer dereference here.

update_subrect() adjusts the sub-rectangle to be inside a base area.
It checks width and height to not exceed those of the area, then it
checks the low border (left or top) to lie within the area, then the
high border (right or bottom) to lie there too. This latter check has
a bug, which is fixed by this patch.

Also, v4l2_subdev_ops structure is passed to a function

After changes to v4l2_clk API introduced in v4.1 by commits a37462b919
'[media] V4L: remove clock name from v4l2_clk API' and 4f528afcfb
'[media] V4L: add CCF support to the v4l2_clk API', ov6650 sensor
stopped responding because v4l2_clk_get(), still called with
depreciated V4L2 clock name "mclk", started to return respective CCF
clock instead of the V4l2 one registered by soc_camera. Fix it by
calling v4l2_clk_get() with NULL clock name.
Created and tested on Amstrad Delta against Linux-4.7-rc3 with

The driver doesn't have a struct of_device_id table but supported devices
are registered via Device Trees. This is working on the assumption that a
I2C device registered via OF will always match a legacy I2C device ID and
that the MODALIAS reported will always be of the form i2c:<device>.
But this could change in the future so the correct approach is to have an
OF device ID table if the devices are registered via OF.

It's no longer necessary to keep the i2c_client in the device struct
unmodified until a sensor is found, so reduce stack usage in
em28xx_probe_sensor_micron() and em28xx_probe_sensor_omnivision() by using
a pointer to the client instead of a local copy.

Previously multiple calls to v4l2_device_register_subdev_nodes() ended up
corrupting memory and leaking some, too. This patch changes the behaviour so
that sub-devices the device nodes of which are already registered are
ignored.

The I2C core always reports a MODALIAS of the form i2c:<foo> even if the
device was registered via OF, this means that exporting the OF device ID
table device aliases in the module is not needed. But in order to change
how the core reports modaliases to user-space, it's better to export it.
Before this patch:
$ modinfo drivers/media/i2c/et8ek8/et8ek8.ko | grep alias
alias: i2c:et8ek8
After this patch:
$ modinfo drivers/media/i2c/et8ek8/et8ek8.ko | grep alias

Several error paths didn't log why an error was returned. Add this.
Also handle the corner case of "adapter is unconfigured AND the message
is from Unregistered to TV AND reply is non-zero" separately and return
EINVAL in that case, since it really is an invalid value and not an
unconfigured CEC device.
