From: Albert Esteve Date: Fri, 8 May 2026 07:04:44 +0000 (+0200) Subject: drm/panel/lxd-m9189a: Use refcounted allocation in place of devm_kzalloc() X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=c8c80bde16784f62b7fa51dfda3b0310c37c623b;p=thirdparty%2Flinux.git drm/panel/lxd-m9189a: 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.
