From: Prabhakar Lad Date: Wed, 26 Nov 2014 22:42:30 +0000 (-0300) Subject: [media] media: s5p-tv: use vb2_ops_wait_prepare/finish helper X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=c747404dbf2dcc0d8cb5d2e8aee5810b6ebba496;p=openwrt%2Fstaging%2Fblogic.git [media] media: s5p-tv: use vb2_ops_wait_prepare/finish helper This patch drops driver specific wait_prepare() and wait_finish() callbacks from vb2_ops and instead uses the the helpers vb2_ops_wait_prepare/finish() provided by the vb2 core, the lock member of the queue needs to be initalized to a mutex so that vb2 helpers vb2_ops_wait_prepare/finish() can make use of it.
