Subject: OMAPDSS: init omap_dss_devices internally
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=9d8232a77fd55e00f0c519518c0ac5bbff1e477c;p=openwrt%2Fstaging%2Fblogic.git

OMAPDSS: init omap_dss_devices internally

Now that each output driver creates their own display devices, the
output drivers can also initialize those devices.
