snd_cobalt_pcm_ioctl() does nothing but calling the default handler. Now PCM core accepts NULL as the default ioctl ops, so let's drop altogether. Signed-off-by:

With the recent change in ALSA PCM core, the whole open-coded vmalloc buffer handling in this driver can be dropped by replacing with the managed buffer allocation. Also, snd_tm6000_capture_free() is dropped since the check of stream_started flag makes no sense; hw_free callback is guaranteed to be called after the stream gets stopped. Signed-off-by:

In csc_set_coeff() we were previously checking if the format type was V4L2_BUF_TYPE_VIDEO_OUTPUT or V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE as a mean to figure out if the format was multiplanar or not. This was not entirely accurate as the format type could also be a CAPTURE type instead. Fix this by removing the 'switch' construct and replacing them with "if (V4L2_TYPE_IS_MULTIPLANAR(type))" instead. Signed-off-by:

Currently if the allocation of new_buf fails then a null pointer dereference occurs when assiging new_buf->vb. Avoid this by returning early on a memory allocation failure as there is not much more can be done at this point.

It is the vfrontporch of field 1 that is one half-line longer, not the backporch. The order of the vertical signals in an interlaced system is: Field 1: vsync vbackporch active video of field 1 vfrontporch + 0.5 Field 2: il_vsync il_vbackporch - 0.5 active video of field 2 il_vfrontporch Interlaced systems that use HALF_LINE set the il_ fields as follows: il_vfrontporch = vfrontporch il_vsync = vsync il_vbackporch = vbackporch + 1 So the total vertical blanking for field 1 is: vsync + vbackporch + vfrontporch + 0.5 and for field 2: vsync + vbackporch + 1 + vfrontporch - 0.5 == vsync + vbackporch + vfrontporch + 0.5 So each field has the same number of half-lines.

Support to emulate touch devices in vivid driver. It generates touch patterns simulating single tap, double tap, triple tap, move from left to right, zoom in, zoom out, palm press simulating large area being pressed on screen, and simulating 16 different simultaneous touch points.The values generated are based on behavior of the rmi_f54 driver.

The AVerMedia CE310B is a simple composite + S-Video + stereo audio capture card, and uses only the CX23888 to perform all of these functions. I've tested both video inputs and the audio interface and confirmed that they're all working. However, there are some issues: * Sometimes when I switch inputs the video signal turns black and can't be recovered until the system is rebooted. I haven't been able to determine the cause of this behavior, nor have I found a solution to fix it or any workarounds other than rebooting. * The card sometimes seems to have trouble syncing to the video signal, and some of the VBI data appears as noise at the top of the frame, but I assume that to be a result of my very noisy RF environment and the card's unshielded input traces rather than a configuration issue.

Currently wait_event_interruptible_timeout is called in cec_thread_func() when adap->transmitting is set. But if the adapter is unconfigured while transmitting, then adap->transmitting is set to NULL. But the hardware is still actually transmitting the message, and that's indicated by adap->transmit_in_progress and we should wait until that is finished or times out before transmitting new messages. As the original commit says: adap->transmitting is the userspace view, adap->transmit_in_progress reflects the hardware state. However, if adap->transmitting is NULL and adap->transmit_in_progress is true, then wait_event_interruptible is called (no timeout), which can get stuck indefinitely if the CEC driver is flaky and never marks the transmit-in-progress as 'done'. So test against transmit_in_progress when deciding whether to use the timeout variant or not, instead of testing against adap->transmitting. Signed-off-by:

WARN if transmit_queue_sz is 0 but do not decrement it. The CEC adapter will become unresponsive if it goes below 0 since then it thinks there are 4 billion messages in the queue. Obviously this should not happen, but a driver bug could cause this. Signed-off-by:

Some messages are allowed to be a broadcast message in CEC 2.0 only, and should be ignored by CEC 1.4 devices. Unfortunately, the check was wrong, causing such messages to be marked as invalid under CEC 2.0. Signed-off-by:

Currently we were using an arbitrarily small maximum resolution mostly based on available sensor capabilities. However the hardware DMA limits are much higher than the statically define maximum resolution we were using. There we rework the boundary check code to handle the maximum width and height based on the maximum line width in bytes and re-calculating the pixel width based on the given pixel format.
