The change in 8280b66 does not cover the case when v4l2_dev is already
NULL, fix that.With a Kinect sensor, seen as an USB camera using GSPCA in this context,
a NULL pointer dereference BUG can be triggered by just unplugging the
device after the camera driver has been loaded.Signed-off-by: Antonio Ospite

The uvc_mc_register_entity() function wrongfully selects the
media_entity associated with a UVC entity when creating links. This
results in access to uninitialized media_entity structures and can hit a
BUG_ON statement in media_entity_create_link(). Fix it.Signed-off-by: Laurent Pinchart

If the bus has been reset on resume, set the alternate setting to 0.
This should be the default value, but some devices crash or otherwise
misbehave if they don't receive a SET_INTERFACE request before any other
video control request.Microdia's 0c45:6437 camera has been found to require this change or it
will stop sending video data after resume.uvc_video.c]

The logic at em28xx_isoc_dvb_max_packetsize() sucks, at least for newer
the needed packet size. Yet, it is better than nothing.Rewrite the code in order to change the default to 752 for em2884 and
newer chips and provide a better way to handle per-chipset specifics.For em2874, the current default should be enough, as the only em2874
board is currently a 1-seg ISDB-T board, so, it needs only a limited
amount of bandwidth.Signed-off-by: Mauro Carvalho Chehab
