From ff370257ed0bba6e98a9538fefa402a4696f9857 Mon Sep 17 00:00:00 2001 From: Nishanth Menon Date: Thu, 27 Mar 2014 11:18:33 -0500 Subject: [PATCH] i2c: omap: fix usage of IS_ERR_VALUE with pm_runtime_get_sync we use IS_ERR_VALUE to check for error values of pm_runtime_get_sync, when the value can only be < 0 in the case of err. Replace the check with a simpler < 0 check. This fixes the coccicheck warnings: linux-2.6/drivers/i2c/busses/i2c-omap.c:1157:5-24: pm_runtime_get_sync returns < 0 as error. Unecessary IS_ERR_VALUE at line 1158 linux-2.6/drivers/i2c/busses/i2c-omap.c:1278:7-26: pm_runtime_get_sync returns < 0 as error.
