Subject[PATCH 3.16.y-ckt 149/183] gpio: rcar: Fix error path for devm_kzalloc() failure
Date
3.16.7-ckt8 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Geert Uytterhoeven <geert+renesas@glider.be>

commit 7d82bf3419c103dbb730e7834186fc5d577b9da1 upstream.

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".
