[media] v4l2-ioctl: Don't assume file->private_data always points to a v4l2_fh · 7a3ed2d9

由 Hans Verkuil 提交于 7月 07, 2012

Commit efbceecd, 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]
[  142.514649]  [<ffffffffa01c7a77>] v4l_queryctrl+0x47/0x90 [videodev]
[  142.517417]  [<ffffffffa01c58b1>] __video_do_ioctl+0x2c1/0x420 [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.

[media] gspca_konica: Fix init sequence · e163609e

由 Hans de Goede 提交于 6月 30, 2012

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.

[media] gspca: Add reset_resume callback to all sub-drivers · 8bb58964

由 Hans de Goede 提交于 6月 30, 2012

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.
