From: Tomi Valkeinen Date: Fri, 11 Jan 2019 03:50:34 +0000 (+0200) Subject: drm/omap: dsi: Fix OF platform depopulate X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=0940c52742de0d2f70ba687bfd5fe8aa38c5f27d;p=openwrt%2Fstaging%2Fblogic.git drm/omap: dsi: Fix OF platform depopulate Commit edb715dffdee ("drm/omap: dss: dsi: Move initialization code from bind to probe") moved the of_platform_populate() call from dsi_bind() to dsi_probe(), but failed to move the corresponding of_platform_depopulate() from dsi_unbind() to dsi_remove(). This results in OF child devices being potentially removed multiple times. Fix it by placing the of_platform_depopulate() call where it belongs.
