From 26a20eb09d44dc064c4f5d1f024bd501c09edb4b Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Thu, 22 Aug 2013 19:51:01 -0300 Subject: [PATCH] [media] v4l: vsp1: Fix mutex double lock at streamon time A mutex_lock() was left when the driver was converted to use the vb2 ioctl helpers, resulting in a deadlock at streamon time. Fix it.
