Subject: [PATCH 0/1] V4L: Event: debugging fixes
Date: Mon, 03 May 2010 18:42:23 +0300 [thread overview]
Message-ID: <4BDEEEDF.7050905@maxwell.research.nokia.com> (raw)
Hi,
Laurent Pinchart found that on uni-processor kernels without spinlock
debugging spin_is_locked() is always zero, which causes a bad WARN_ON()
message to be shown. The following patch removes the WARN_ON() and
replaces it with assert_spin_locked() which works correctly.
Regards,
