| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When suspending a device while a video stream is active all buffers marked as done but not dequeued yet will be kept across suspend and given back to userspace after resume. This will result in outdated buffers being dequeued. Introduce a new vb2 function to mark all done buffers as erroneous instead, to be used by drivers at resume time.

| * [media] omap3isp: Cancel all queued buffers when stopping the video streamLaurent Pinchart2014-05-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | When stopping a video stream the driver waits for ongoing DMA opeations to complete for the currently active buffer, but doesn't release the non-active queued buffers. This isn't a problem in most cases as the video device is usually closed after the stream is stopped, which will release all the buffers. However the problem would generate a warning when switching to videobuf2. Fix it by cancelling all buffers after DMA operations have completed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 16-bit registers are read through two 8-bit read operations. Factorize that common pattern into 16-bit read accessors to simplify the code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We do not want to modify the info string arrays ever, so no need to waste stack space for them. While we are at it also make them const.
