| |
3.0-stable review patch. If anyone has any objections, please let us know.
------------------
From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= <u.kleine-koenig@pengutronix.de>
commit e57ee01750c4954fd0b5e3c6109cd4b870880eb9 upstream.
Using __SPIN_LOCK_UNLOCKED for a dynamically allocated lock is wrong and breaks the build with PREEMPT_RT_FULL.
