* [media] davinci: vpif: add check for genuine interrupts in the isrManjunath Hadli2012-07-303-0/+21
| | | | | | | | | | | | 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.

* [media] videobuf-dma-contig: restore buffer mapping for uncached bufersLad, Prabhakar2012-07-301-21/+32
| | | | | | | | | | | | | | | from commit a8f3c203e19b702fa5e8e83a9b6fb3c5a6d1cce4 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.

* [media] v4l2-ioctl: Don't assume file->private_data always points to a v4l2_fhHans Verkuil2012-07-301-7/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | Commit efbceecd4522a41b8442c6b4f68b4508d57d1ccf, 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 sequenceHans de Goede2012-07-301-10/+18
| | | | | | | | | | | | | | 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-driversHans de Goede2012-07-3041-2/+41
| | | | | | | | | | | | | | | | | | 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.
