From: Yong He <yong.m...@intel.com> Subject: [PATCH] MRST Tablet camera driver ver-0.959, fix 9947
Bug 9947 - when switch to a new resolution,
Back camera need to skip first frame after turn on streaming
move the delay to ISP for snapshot only (preview do not need delay)
and increase the total delay time to 450 (3 frame) in order to get
good picture quality
