Subject: drm/tidss: oldi: convert to devm_drm_bridge_alloc() API
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b213eb34f857c45bdd769c9e9191a386accc9e8f;p=thirdparty%2Flinux.git

drm/tidss: oldi: convert to devm_drm_bridge_alloc() API

DRM bridges now use "devm_drm_bridge_alloc()" for allocation and
initialization. "devm_kzalloc()" is not allowed anymore and it results
in WARNING. So convert it.
