From ffeb9ec72e18e16d0b0835d959cdf01650758638 Mon Sep 17 00:00:00 2001 From: Andrew Morton Date: Sat, 26 May 2007 07:54:21 -0300 Subject: [PATCH] V4L/DVB (5699): Cinergyt2: fix file release handler If this mutex_lock_interruptible() does fail due to signal_pending() then the state of the driver will get trashed in interesting ways, because userspace cannot and will not retry the close().
