The following patch fixes code that checks for CX88_VMUX_TELEVISION, but not CX88_VMUX_CABLE. This prevented for example the audio standard from being set when using the cable input. Signed-off-by:

Fix a divide-by-zero error in ds3000's ds3000_read_snr(), when getting a very low signal reading (dvbs2_signal_reading >= 1). This prevents some nasty EIPs when running szap-s2 with a very low signal strength. Signed-off-by:

Due to obvious copy and paste coding a number of video capture drivers which implement a limit on the buffer memory decremented the user supplied buffer count in a while loop until it reaches an acceptable value. This is a silly thing to do when the maximum value can be directly computed. Signed-off-by:

This reverts commit bc52d6eb. On newer kernels, a saa7134 board stopped to display TV video output properly. After a bisect, I found it as the commit causing the issue. Turns out that v4l_bound_align_image isn't doing the same bounding calculation as manually done previously in saa7134_try_fmt_vid_cap. What isn't equal is the calculation done in clamp align, while previously it did "f->fmt.pix.width &= ~0x03", clamp_align function does "Round to nearest aligned value" as stated in the comment, which yields a different result. If I comment the round calculation in clamp_align like this: "x = (x /*+ (1 << (align - 1))*/) & mask", I get it fixed too, because this way the calculation is the same then. Signed-off-by:

Note that I have not been able to find anyone with this hardware. I tried contacting the author without success, searched on eBay and similar places without luck either. So this conversion is untested. That said, it was pretty straightforward so it is time to have this driver join the V4L2 world at last. Signed-off-by:

The usbvision driver created vbi device nodes but the actual implementation was just stubs and only returned errors to userspace. In addition it used video_usercopy() and we want to remove that eventually. So remove all the vbi code except for the vbi flag in the card definition should someone ever be mad enough to work on a proper implementation for this driver. Signed-off-by:

If the ioctl was defined without direction (e.g. _IO('o', 25)), then the arg as passed to vidioc_default was NULL instead of the original argument. Several ioctls in e.g. include/linux/dvb/video.h and audio.h use this type of ioctl to pass simple numerical values to the driver. Signed-off-by: -

For some reason the definition of enum v4l2_ctrl_type is far from the place where it is actually needed. This makes it hard to work with this header. Move it to just before struct v4l2_queryctrl, which is the one that actually uses it. Signed-off-by:

If the kmalloc() failed for "ccdc_cfg = kmalloc(...);" then we would exit with the lock held. I moved the mutex_lock() below the allocation because it isn't protecting anything in that block and allocations are allocations are sometimes slow. Signed-off-by:

ir-core.h has the kABI to be used by the bridge drivers, when needing to register IR protocols and pass IR events. However, the same file also contains IR subsystem internal calls, meant to be used inside ir-core and between ir-core and the raw decoders. Better to move those functions to an internal header, for some reasons: 1) Header will be a little more cleaner; 2) It avoids the need of recompile everything (bridge/hardware drivers, etc), just because a new decoder were added, or some other internal change were needed; 3) Better organize the ir-core API, splitting the functions that are internal to IR core and the ancillary drivers (decoders, lirc_dev) from the features that should be exported to IR subsystem clients.

drivers/media/IR/ir-raw-event.c is currently written with the assumption that all "raw" hardware will generate events only on state change (i.e. when a pulse or space starts). However, some hardware (like mceusb, probably the most popular IR receiver out there) only generates duration data (and that data is buffered so using any kind of timing on the data is futile). Furthermore, using signed int's to represent pulse/space durations is a well-known approach when writing ir decoders. With this patch: - s64 int's are used to represent pulse/space durations in ns - a workqueue is used to decode the ir protocols outside of interrupt context - #defines are added to make decoders clearer - decoder reset is implemented by passing a zero duration to the kfifo queue and decoders are updated accordingly Signed-off-by:
