Hi Andrzej, > From: Andrzej Hajda [mailto:a.hajda@xxxxxxxxxxx] > Sent: Friday, October 02, 2015 2:10 PM > > MFC driver never delivered EOS event to apps feeding constantly its capture > buffer with fresh buffers. The patch fixes it by marking last buffers returned > by MFC with MFC_BUF_FLAG_EOS flag and firing EOS event on de-queuing > such buffers. Checkpatch complains that lines in the description are too long.
