From: Albert Esteve Date: Fri, 8 May 2026 07:04:41 +0000 (+0200) Subject: drm/panel/visionox-g2647fb105: Use refcounted allocation in place of devm_kzalloc() X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=acc11bdc5b1191f75be7df25aae5adf82f1bed24;p=thirdparty%2Fkernel%2Flinux.git drm/panel/visionox-g2647fb105: Use refcounted allocation in place of devm_kzalloc() Move to using the new API devm_drm_panel_alloc() to allocate the panel. In the call to the new API, avoid using explicit type and use __typeof() for more type safety. Also deduplicate the prepare_prev_first assignment that was set both before and after drm_panel_init().
