Subject: gpio: rcar: Fix error path for devm_kzalloc() failure
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=7d82bf3419c103dbb730e7834186fc5d577b9da1;p=linux-beck.git

gpio: rcar: Fix error path for devm_kzalloc() failure

If the call to devm_kzalloc() fails, nothing must be cleant up.
This was missed before because gpio_rcar_probe() had a "return"
statement after the first "goto err0".
