From: Laurent Pinchart Date: Fri, 8 Jun 2018 13:39:27 +0000 (+0300) Subject: drm/omap: hdmi: Constify video mode and related pointers X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=95e472da1094dfe41b7d1d3fb2d04486cf863a42;p=openwrt%2Fstaging%2Fblogic.git drm/omap: hdmi: Constify video mode and related pointers Constify many pointers to struct videomode, as well as pointers to container structures, to ensure the video mode isn't modified after the .check_timings() operation.
