2020-03-02media: usbvision: deprecate driverHans Verkuil
The driver is deprecated and scheduled for removal by the end of 2020. The reason is that this driver is for old and obsolete hardware, and it produces a continuous stream of syzbot errors due to poor code. In order to prevent removal the following actions would have to be taken: - clean up the code - convert to the vb2 framework - fix the disconnect and free-on-last-user handling (i.e., add a release callback for struct v4l2_device and rework the code to use that correctly).

2019-07-22media: media/usb: don't set description in ENUM_FMTHans Verkuil
The V4L2 core sets the description for the driver in order to ensure consistent naming. So drop the strscpy of the description in drivers. Also remove any description strings in driver-internal structures since those are no longer needed.

While the wakeup path seems to be set up, this waitqueue is actually never used as no-one enqueues themselves on the list. As such, wakeups are meaningless without waiters, so lets just get rid of the whole thing.

Drop the FSF's postal address from the source code files that typically contain mostly the license text. Of the 628 removed instances, 578 are outdated. The patch has been created with the following command without manual edits: git grep -l "675 Mass Ave\|59 Temple Place\|51 Franklin St" -- \ drivers/media/ include/media|while read i; do i=$i perl -e ' open(F,"< $ENV{i}"); $a=join("", <F>); $a =~ s/[ \t]*\*\n.*You should.*\n.*along with.*\n.*(\n.*USA.*$)?\n//m && $a =~ s/(^.*)Or, (point your browser to) /$1To obtain the license, $2\n$1/m; close(F); open(F, "> $ENV{i}"); print F $a; close(F);'; done Signed-off-by: Sakari Ailus <sakari.ailus@linux.intel.com>

2015-08-11[media] usbvision: remove power_on_at_open and timed power offHans Verkuil
This causes lots of problems and is *very* slow as well. One of the main problems is that this prohibits the use of the control framework since subdevs will be unloaded on power off which is not allowed as long as they are used by a usb device. Apparently the reason for doing this is to turn off a noisy tuner. My hardware has no problem with that, and I wonder whether the hardware with that noisy tuner wasn't just functioning improperly as I have never heard of noisy tuners. Contact me if you have one of those devices and I can take a look whether the tuner can't be powered off if necessary by letting the tuner subdevice go into standby mode. Unloading the tuner module is just evil and is not the right approach. Signed-off-by: Hans Verkuil <hans.verkuil@cisco.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@osg.samsung.com>
