From: Mauro Carvalho Chehab <mchehab@infradead.org> kernel-sync: Author: Jeff Garzik <jgarzik@redhat.com> [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. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
