Subject: [PATCH 7/7] Input: cyttsp - consolidate PM methods
Date: Mon, 14 Nov 2011 00:16:17 -0800	[thread overview]
Message-ID: <20111114081617.10141.41781.stgit@hammer.corenet.prv> (raw)
In-Reply-To: <20111114080939.10141.46174.stgit@hammer.corenet.prv>

The PM methods are basically the same for SPI and I2C busses, so let's
use the same dev_pm_ops for both of them.
