Jorge Ramirez-Ortiz 5d5de3eba4 avcodec: v4l2_m2m: remove unnecessary timeout. Qualcomm's db410c/db820 Venus driver currently present in mainline kernel has a bug which mishandles the CMD_STOP requests causing the decoder to block while draining [1]. This patch removes the workaround that was used to prevent that situation. Encoding/Decoding tested on db820c. [1] on CMD_STOP, the driver is flushing all buffers and never raising IPIPE which ends up in blocking on poll.		2018-01-21 00:37:35 +00:00
