Shuah Khan 050b6c98b4 [media] media: au0828 enable the right media source when input changes
Change vidioc_s_input() to enable the media source for the newly
selected input.

v4l2-core enables source before calling au0828's vidioc_s_input()
handler. Hence, when input selection changes, media source for the
newly selected input needs to be enabled.

Shuah Khan 174ced212c [media] media: au0828 set ctrl_input in au0828_s_input()
dev->ctrl_input is set in vidioc_s_input() and doesn't get set in
au0828_s_input(). As a result, dev->ctrl_input is left uninitialized
until user space calls s_input.

It works correctly because the default input value is 0 and which is
what dev->ctrl_input gets initialized via kzalloc().

Change to set dev->ctrl_input in au0828_s_input(). Also optimize
vidioc_s_input() to return if the new input value is same as the
current.

Heiner Kallweit 449c1fcd86 [media] media: rc: nuvoton: support reading / writing wakeup sequence via sysfs
This patch adds a binary attribute /sys/class/rc/rc?/wakeup_data which
allows to read / write the wakeup sequence.

In combination with the core extension for exposing the most recent raw
packet this allows to easily define and set a wakeup sequence.

At least on my Zotac CI321 the BIOS resets the wakeup sequence at each boot
to a factory default. Therefore I use a udev rule
SUBSYSTEM=="rc", DRIVERS=="nuvoton-cir", ACTION=="add", RUN+="<script>"
with the script basically doing
cat <stored wakeup sequence> >/sys${DEVPATH}/wakeup_data

The device initialization completes only after calling
input_register_device(). However, rc_open() can be called while
the device is being registered by the input/evdev core. So, we
can't expect that rc_dev->initialized to be true.

Change the logic to don't require initialized == true at rc_open
and change the type of initialized to be atomic.

this way, we can check for it earlier where it is really needed,
without needing to lock the mutex just for testing it.

Mauro Carvalho Chehab b6554ea551 [media] drxj: don't do math if not needed
While there's no risk of divison by zero, the logic there is akward, as it
does the calculus for the numerator and denominator before checking
if this will be used.

Change the order to check first if the denominator is zero, and only
calculating the numerator/denominator if not.

This should also avoid those smatch errors:

Mauro Carvalho Chehab f6f7b58ef0 [media] airspy: fix bit set/clean mess on s->flags
As warned by smatch:
	drivers/media/usb/airspy/airspy.c:541 airspy_start_streaming() warn: test_bit() takes a bit number
	drivers/media/usb/airspy/airspy.c:569 airspy_start_streaming() warn: test_bit() takes a bit number
	drivers/media/usb/airspy/airspy.c:605 airspy_stop_streaming() warn: test_bit() takes a bit number

set_bit/clear_bit argument is the bit number, and not 1 << bit.

Thankfully, one of the bits was not used (URB_BUF), with would
otherwise cause a driver misfunctioning.

Clean this mess by always using set_bit/clear_bit/test_bit and
removing the unused bit.

Wesley Post f7c7ac480d [media] gspca: Fix ov519 i2c r/w not working when connected to a xhci host
Fix the ov519 driver not working (unable to talk to the sensor) when
plugged into a xhci host. The root cause here is that uhci/ohci/ehci
hosts typically will send any pending async requests every milli-second
and then go to sleep for the rest if the milli-second, where as xhci hosts
send them immediately, causing things to go too fast for the ov519 bridge.

This commit adds a few delays fixing this.

Hans de Goede 5c915c6876 [media] bttv: Width must be a multiple of 16 when capturing planar formats
On my bttv card "Hauppauge WinTV [card=10]" capturing in YV12 fmt at max
size results in a solid green rectangle being captured (all colors 0 in
YUV).

This turns out to be caused by max-width (924) not being a multiple of 16.

We've likely never hit this problem before since normally xawtv / tvtime,
etc. will prefer packed pixel formats. But when using a video card which
is using xf86-video-modesetting + glamor, only planar XVideo fmts are
available, and xawtv will chose a matching capture format to avoid needing
to do conversion, triggering the solid green window problem.
