[PATCH] regulator: fixed: Remove WARs for handling of_get_named_gpio() return

From: Laxman Dewangan
Date: Thu Mar 10 2016 - 07:26:16 EST


The GPIO interface of_get_named_gpio() has implemented the proper
error returns even EPROBE_DEFER and hence caller need not to
implement any WAR for translating the returned error.

Remove the WAR implemented in fixed regulator to handle the
return of of_get_named_gpio().
