drivers/media/pci/bt8xx/bttv-audio-hook.c:371 adtvk503_audio() warn: bitwise AND condition is false here
there are some serious issues at the audio hook implementation.
They're not following what's specified at the DocBook:
http://linuxtv.org/downloads/v4l-dvb-apis/vidioc-g-tuner.html#tuner-audmode
Basically, it was assuming that the audmode (V4L2_TUNER_MODE_foo)
is a variable with a bit maskk. However, it isn't.
The bitmask only applies to rxsubchans field (V4L2_TUNER_SUB_foo).
As the code is also too complex, and not all hooks were returning
both audmode and rxsubchans to a VIDIOC_G_TUNER, rewrite the
functions, in order to fix both for get and set tuner ioctls.

The indentation on this driver were deadly broken. On lots
of places, it was using 4 spaces instead of tab to indent.
On other parts, it were using tabs.
Also, on several places, it were not even being properly aligned,
as reported by smatch:

drivers/media/dvb-frontends/dib0070.c:713 dib0070_reset() warn: inconsistent indenting
My first idea were to leave it as-is or to just touch the above.
However, this won't be fixing anything. So, as painful as it
is, let's fix indentation globally on the driver, and then
address the inconsistencies.
Hopefully, this driver doesn't have much patches, so it likely
won't conflict to any other patch during this merge window.
Besides the big size of this patch, no functional changes
were done.

ov7670_s_exp() checks read error for 2 registers: REG_COM1
and REG_COM8. But, although it uses the value latter, it
doesn't check errors on REG_AECHH read. Yet, as it is doing
a bitmask operation there, the read operation should succeed.
So, fix the code to also check if this succeeded.
This fixes this smatch report:

As reported by smatch:
drivers/media/usb/gspca/zc3xx.c:5994 transfer_update() info: ignoring unreachable code.
That happens because there's a return that it is never called,
as the work queue runs an infinite loop, except when the device is
put to sleep or an error happens.
When an error happens, a break statement is enough to go out of
the loop. So, let's remove the goto, as break is the typical
instruction used to end a loop.
