From f000fd80937c0d94c67f9f3e7026f1fbc8ef8873 Mon Sep 17 00:00:00 2001 From: Jeff Garzik Date: Tue, 22 Apr 2008 13:50:34 +0200 Subject: [ALSA] Fix synchronize_irq() bugs, redundancies free_irq() calls synchronize_irq() for you, so there is no need for drivers to manually do the same thing (again). Thus, calls where sync-irq immediately precedes free-irq can be simplified. However, during this audit several bugs were noticed, where free-irq is preceded by a "irq >= 0" check... but the sync-irq call is not covered by the same check. So, where sync-irq could not be eliminated completely, the missing check was added.
