From 524c6e04f826cea8a34a27136d8f5925df9213ed Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sat, 3 Sep 2016 01:17:20 +0200 Subject: dmaengine: sirf: fix irq number error check irq_of_parse_and_map() returns 0 on error, no NO_IRQ, so the failure condition can never be met. This changes the comparison to check for zero instead.
