Subject: [PATCH 01/10] media: omap3isp: remove unused clkdev
Date: Mon, 02 Mar 2015 17:06:06 +0000	[thread overview]
Message-ID: <E1YSTnC-0001JU-CX@rmk-PC.arm.linux.org.uk> (raw)
In-Reply-To: <20150302170538.GQ8656@n2100.arm.linux.org.uk>

No merged platform supplies xclks via platform data.  As we want to
slightly change the clkdev interface, rather than fixing this unused
code, remove it instead.
