media: saa7134: fix regression with tvtime

2014-07-01T03:13:59+00:00

commit 17e7f1b515803e1a79b246688aacbddd2e34165d upstream. This solves this bug: https://bugzilla.kernel.org/show_bug.cgi?id=73361 The problem is that when you quit tvtime it calls STREAMOFF, but then it queues a bunch of buffers for no good reason before closing the file descriptor. In the past closing the fd would free the vb queue since that was part of the file handle struct. Since that was moved to the global struct that no longer happened. This wouldn't be a problem, but the extra QBUF calls that tvtime does meant that the buffer list in videobuf (q->stream) contained buffers, so REQBUFS would fail with -EBUSY. The solution is to init the list head explicitly when releasing the file descriptor and to not free the video resource when calling streamoff. The real fix will hopefully go into kernel 3.16 when the vb2 conversion is merged. Basically the saa7134 driver with the old videobuf is so full of holes it ain't funny anymore, so consider this a band-aid for kernels 3.14 and 15.

media: uvcvideo: Fix clock param realtime setting

2014-07-01T03:13:58+00:00

commit 3b35fc81e7ec552147a4fd843d0da0bbbe4ef253 upstream. timestamps in v4l2 buffers returned to userspace are updated in uvc_video_clock_update() which uses timestamps fetched from uvc_video_clock_decode() by calling unconditionally ktime_get_ts(). Hence setting the module clock param to realtime has no effect before this patch. This has been tested with ffmpeg: ffmpeg -y -f v4l2 -input_format yuyv422 -video_size 640x480 -framerate 30 -i /dev/video0 \ -f alsa -acodec pcm_s16le -ar 16000 -ac 1 -i default \ -c:v libx264 -preset ultrafast \ -c:a libfdk_aac \ out.mkv and inspecting the v4l2 input starting timestamp.

media: exynos4-is: Fix compilation for !CONFIG_COMMON_CLK

2014-07-01T03:13:58+00:00

commit f486e7c3cb9849b6a661931fa8c51a43d477046b upstream. CONFIG_COMMON_CLK is not enabled on S5PV210 platform, so include some clk API data structures conditionally to avoid compilation errors. These #ifdefs will be removed for next kernel release, when the S5PV210 platform moves to DT and the common clk API.

media: exynos4-is: Free FIMC-IS CPU memory only when allocated

2014-07-01T03:13:58+00:00

commit 404a90abc60f60df2757cb272660e003d326881f upstream. Ensure dma_free_coherent() is not called with incorrect arguments and only when the memory was actually allocated. This will prevent possible crashes on error paths of the top level media device driver, when fimc-is device gets unregistered and its driver detached.

media: stk1160: Avoid stack-allocated buffer for control URBs

2014-07-01T03:13:57+00:00

commit 85ac1a1772bb41da895bad83a81f6a62c8f293f6 upstream. Currently stk1160_read_reg() uses a stack-allocated char to get the read control value. This is wrong because usb_control_msg() requires a kmalloc-ed buffer. This commit fixes such issue by kmalloc'ating a 1-byte buffer to receive the read value. While here, let's remove the urb_buf array which was meant for a similar purpose, but never really used.
