Subject: [media] media: omap3isp: remove unused clkdev
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=befd25a2bd61f1706508280f705e18be8b283e3e;p=openwrt%2Fstaging%2Fblogic.git

[media] media: omap3isp: remove unused clkdev

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.
