Subject: thermal: spear13xx: checking for NULL instead of IS_ERR()
X-Git-Tag: v3.4-rc6~7^2~3^9~4
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=03ee62f0b9919535a1be02f72fe8153255a7fda0;p=profile%2Fivi%2Fkernel-x86-ivi.git

thermal: spear13xx: checking for NULL instead of IS_ERR()

thermal_zone_device_register() never returns NULL, on error it returns and
ERR_PTR().
