From: Geert Uytterhoeven Date: Fri, 30 Jun 2017 06:57:39 +0000 (+0200) Subject: pinctrl: rza1: Remove unneeded wrong check for wrong variable X-Git-Tag: v4.13-rc1~139^2~2 X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=ea4083165fbb322b69a59588a283b7c98bd42db3;p=linux.git pinctrl: rza1: Remove unneeded wrong check for wrong variable Depending on compiler version: drivers/pinctrl/pinctrl-rza1.c: In function ‘rza1_pinctrl_probe’: drivers/pinctrl/pinctrl-rza1.c:1260:5: warning: ‘ret’ may be used uninitialized in this function [-Wmaybe-uninitialized] if (ret) ^ Indeed, the result returned by platform_get_resource() was stored in "res", not "ret". In addition, the correct error check would be "if (!res)", as platform_get_resource() does not return an error code, but returns NULL on failure. However, as devm_ioremap_resource() verifies the validity of the passed resource pointer anyway, the check can just be removed.
