From: Greg KH
Date: Wed Aug 03 2011 - 19:45:47 EST


3.0-stable review patch. If anyone has any objections, please let us know.

commit e57ee01750c4954fd0b5e3c6109cd4b870880eb9 upstream.

Using __SPIN_LOCK_UNLOCKED for a dynamically allocated lock is wrong and
breaks the build with PREEMPT_RT_FULL.
