2011-03-21[media] staging/cx25721: serialize access to devlistArnd Bergmann
Out of the three files accessing the device list, one uses a mutex, one uses the BKL and one does not have any locking. That is of course pointless, so let's make all of them use the same mutex, and get rid of one more BKL user.

It should be enough to avoid compilation breakage, but, as BKL will be removed, we need to properly fix it on a latter patch.

2010-12-30[media] v4l: fix handling of v4l2_input.capabilitiesHans Verkuil
The v4l core sets the v4l2_input.capabilities field based on the supplied v4l2_ioctl_ops. However, several drivers do a memset or memcpy of the v4l2_input struct, thus overwriting that field incorrectly. Either remove the memset (which is already done by the v4l core), or add the proper capabilities field in case of a memcpy. The same is also true for v4l2_output, but that only affected the ivtv driver. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
