From: Geert Uytterhoeven Date: Tue, 4 Aug 2015 13:22:10 +0000 (+0200) Subject: drm/fb-helper: Clarify drm_fb_helper_restore_fbdev_mode*() X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=3d9e35a92e935e1f968e79f0e0b72ce4b9f14c3e;p=openwrt%2Fstaging%2Fblogic.git drm/fb-helper: Clarify drm_fb_helper_restore_fbdev_mode*() As of commit 5ea1f752ae04be40 ("drm: add drm_fb_helper_restore_fbdev_mode_unlocked()"), drm_fb_helper_restore_fbdev_mode() is no longer public, and drivers should call drm_fb_helper_restore_fbdev_mode_unlocked() from their ->lastclose callbacks instead. Update the documentation to reflect this, and absorb the one liner drm_fb_helper_restore_fbdev_mode() into its single caller.
