From 69052167b48fb6878001073cfe44f5b1949538ae Mon Sep 17 00:00:00 2001 From: Dmitry Torokhov Date: Fri, 14 Nov 2014 13:39:05 -0800 Subject: [PATCH] sata_fsl: fix error handling of irq_of_parse_and_map commit aad0b624129709c94c2e19e583b6053520353fa8 upstream. irq_of_parse_and_map() returns 0 on error (the result is unsigned int), so testing for negative result never works.
