From 92311c3c70f9b7f1b7860c2fc2ada09b4d43bfea Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 12 Jun 2012 09:46:26 +0800 Subject: pda_power: Complain if regulator operations fail Rather than silently ignoring errors from the regulator enable and disable add a WARN_ON() - it's probably pretty important if we're not getting power, though it should be vanishingly unlikely in production.
