[media] bttv: remove unneeded locking comments
|
|
|
|
After Mauro's "bttv: Fix locking issues due to BKL removal code" there
|
|
are a number of comments that are no longer needed about lock ordering.
|
|
Remove them.

[media] bttv: fix mutex use before init (BZ#24602)
|
|
|
|
Fix a regression where bttv driver causes oopses when loading, since it
|
|
were using some non-initialized mutexes. While it would be possible to
|
|
fix the issue, there are some other lock troubles, like to the presence of
|
|
lock code at free_btres_lock().
|
|
|
|
It is possible to fix, but the better is to just use the core-assisted
|
|
locking schema. This way, V4L2 core will serialize access to all
|
|
ioctl's/open/close/mmap/read/poll operations, avoiding to have two
|
|
processes accessing the hardware at the same time. Also, as there's just
|
|
one lock, instead of 3, there's no risk of dead locks.
|
|
|
|
The net result is a cleaner code, with just one lock.

rc/ene_ir: fix oops on module load
|
|
|
|
dev->rdev is accessed in ene_setup_hw_settings, so it needs to be wired
|

up before then. Also fix a possible improper resource freeing bug.

rc/imon: need to submit urb before ffdc type check

Otherwise, we have a null receive buffer, and the logic all falls down,

rc/imon: fix ffdc device detection oops
|
|
|
|
There's a nasty bug that slipped in when the rc device interface was
|
|
altered, only affecting the older 0xffdc imon devices. We were trying
|
|
to access ictx->rdev->allowed_protos before ictx->rdev had been set.
|
|
|
|
There's also an issue with call ordering that meant the correct
|
|
keymap wasn't getting loaded for MCE IR type 0xffdc devices.
