Subject: V4L/DVB (6274): V4L: vivi.c replace logic in vivi_poll with videobuf_poll_stream
X-Git-Tag: v2.6.24-rc1~1463^2~31
X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=85c7c70bc241d506dffc1879158f77f8aac69734;p=linux-2.6-omap-h63xx.git

V4L/DVB (6274): V4L: vivi.c replace logic in vivi_poll with videobuf_poll_stream

Since vivi is using videobuf_read_stream() it can use videobuf_poll_stream()
now.
