Hans Verkuil 1a17a942cd [media] vivi: remove pointless video_nr++
Remove the pointless video_nr++. It doesn't do anything useful and it has
the unexpected side-effect of changing the video_nr module option, so
cat /sys/module/vivi/parameters/video_nr gives a different value back
then what was specified with modprobe.

Sylwester Nawrocki f0476a83d6 [media] V4L: Add capability flags for memory-to-memory devices
This patch adds new V4L2_CAP_VIDEO_M2M and V4L2_CAP_VIDEO_M2M_MPLANE
capability flags that are intended to be used for memory-to-memory (M2M)
devices, instead of ORed V4L2_CAP_VIDEO_CAPTURE and V4L2_CAP_VIDEO_OUTPUT.

V4L2_CAP_VIDEO_M2M flag is added at the drivers, CAPTURE and OUTPUT
capability flags are left untouched and will be removed in future,
after a transition period required for existing applications to be
adapted to check only for V4L2_CAP_VIDEO_M2M.

As the same interrupt is shared between capture and display devices,
sometimes we get isr calls where the interrupt might not genuinely belong
to capture or display. Hence, add a condition in the isr to check for
interrupt ownership and channel number to make sure we do not
service wrong interrupts.

This driver consists of 2 parts, a generic tea5777 driver and a driver
for the Griffin radioSHARK v2 USB radio receiver, which is the only driver
using the generic tea5777 for now.

This first version only implements FM support, once the the new
VIDIOC_ENUM_FREQ_BANDS API is upstream I'll also add AM support.

Hans Verkuil 7a3ed2d95e [media] v4l2-ioctl: Don't assume file->private_data always points to a v4l2_fh
Commit efbceecd45, adds a number of helper
functions for ctrl related ioctls to v4l2-ioctl.c, these helpers assume that
if file->private_data != NULL, it points to a v4l2_fh, which is only the case
for drivers which actually use v4l2_fh.

This breaks for example bttv which use the "filedata" pointer for its own uses,
and now all the ctrl ioctls try to use whatever its filedata points to as
v4l2_fh and think it has a ctrl_handler, leading to:

[  142.499214] BUG: unable to handle kernel NULL pointer dereference at 0000000000000021
[  142.499270] IP: [<ffffffffa01cb959>] v4l2_queryctrl+0x29/0x230 [videodev]

[  142.520116]  [<ffffffffa01c7ee6>] video_usercopy+0x1a6/0x470 [videodev]
...

This patch adds the missing test_bit(V4L2_FL_USES_V4L2_FH, &vfd->flags) tests
to the ctrl ioctl helpers v4l2_fh paths, fixing the issues with for example
the bttv driver.

The konica needs a freaking large time (circa 6.5 seconds) to "boot", and
does not want to be bothered while doing so, so sleep for 6 seconds, and
then query its status register at 100ms intervals until it becomes ready.

This removes the "reg_w err: -32" messages shown in dmesg whenever a
konica cam gets initialized, and also fixes the camera not working when
an app tries to use it directly after it has been plugged in and after
a suspend/resume cycle.

Hans de Goede 8bb58964bc [media] gspca: Add reset_resume callback to all sub-drivers
1) The gspca-core's suspend/resume code is such that resume being called after
a reset is safe / ok.

2) All devices tested sofar seem to need the reset_resume callback to work
properly over a suspend

3) The USB-core won't call the reset_resume callback for devices which don't
need it

Thus it seems the simplest and the best to just add the callback to all
sub-drivers, rather then adding the callbacks one-by-one as each driver gets
tested with suspend/resume.
