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. Reported-by: Stephen Rothwell <sfr@canb.auug.org.au> Fixes: 5a49b644b3075f88 ("pinctrl: Renesas RZ/A1 pin and gpio controller") Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
