Subject: [PATCH] gpiolib: fix callers of gpiochip_remove
Date: Tue, 30 Sep 2014 15:24:08 +0200	[thread overview]
Message-ID: <2923496.zl6JUbOQrZ@wuerfel> (raw)

A recent API change made gpiochip_remove return void instead of an
error value, which broke drivers that use this return value:

gpio/gpio-sch311x.c: In function 'sch311x_gpio_probe':
gpio/gpio-sch311x.c:286:7: error: void value not ignored as it ought to be
   if (gpiochip_remove(&priv->blocks[i].chip))
       ^

This changes the callers that I have found during randconfig testing
so they no longer depend on the error code.
