From mboxrd@z Thu Jan 1 00:00:00 1970 From: arnd@arndb.de (Arnd Bergmann) Date: Sat, 3 Sep 2016 01:17:20 +0200 Subject: [PATCH] dmaengine: sirf: fix irq number error check Message-ID: <20160902231737.1721916-1-arnd@arndb.de> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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.
