Subject: [PATCH 1/2] mfd: wm8994: Remove unneeded check for JACKDET
Date: Wed, 17 Jul 2013 13:16:08 +0100 [thread overview]
Message-ID: <1374063369-20444-1-git-send-email-broonie@kernel.org> (raw)
From: Mark Brown <broonie@linaro.org>
The jack detection code holds runtime PM references when required so
there is no need for suspend to do any checks.
