From 0e0809a58869e3e422985f868ad5e0da1fc0ba85 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 26 Sep 2010 09:01:26 -0300 Subject: V4L/DVB: videobuf: add queue argument to videobuf_waiton() videobuf_waiton() must unlock and relock ext_lock if it has to wait. For that to happen it needs the videobuf_queue pointer. Don't attempt to unlock/relock q->ext_lock unless it was locked in the first place. vb->state has to be protected by a spinlock to be safe. This patch is based on code from Mauro Carvalho Chehab .
