From a3b55791b5b2b4b6d31ece9b3975466ec2f07b1b Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Fri, 18 Mar 2011 15:15:11 +0200 Subject: [PATCH 1/7] ASoC: tlv320dac33: Fix inconsistent spinlock usage The lock is used within the interrupt handler. Correct the spinlock usage, and use irqsave/irqrestore flavour of spin_lock/unlock.
