[ Upstream commit 914941827aad5ecddf9bf3a6dee67fbec1af1fff ]
This fixes several issues found with 'v4l2-compliance -s':
1) read()/write() is supported, but not reported in the capabilities 2) S_STD(G_STD()) failed: setting the same standard should just return 0. 3) G_PARM failed to set readbuffers. 4) different field values in the format vs. what v4l2_buffer reported. 5) zero the sequence number when starting streaming. 6) drop VB_USERPTR: makes no sense with dma_contig streaming.
