from commit a8f3c203 restore the mapping scheme for uncached buffers, which was changed in a common scheme for cached and uncached. This apparently was wrong, and was probably intended only for cached buffers. the fix fixes the crash observed while mapping uncached buffers. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:

When the v4l2_device release handler gets called the kobject under vdev->dev has already been released, so we cannot use kobject_name on it (which video_device_node_name does). Signed-off-by:

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.

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.

Various gspca-subdrivers have a JPEG quality control which only changes the quantization tables in the JPEG headers send to user-space without making any changes to the settings of the bridge. Remove these bogus / wrong controls. Signed-off-by:

Changes by Hans de Goede: -rework how gain controls work to better match control framework -make awb + gain + red/blue-balance a single auto-cluster -only add the HFLIP control for TAS5130a sensor cams, as it breaks the video on other cams Signed-off-by:
