Subject: [PATCH] [media] media: davinci_vpfe: fix missing unlock on error in
vpfe_prepare_pipeline()
Add the missing unlock before return from function
vpfe_prepare_pipeline() in the error handling case.
video->lock is lock/unlock in function vpfe_open(),
and no need to unlock it here, so remove unlock
video->lock.
