From: Anusha Srivatsa Date: Fri, 11 Jul 2025 04:31:23 +0000 (-0500) Subject: drm/panel/himax-hx83102: Use refcounted allocation in place of devm_kzalloc() X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=46c8779be619159a9774846b022286fbf861fe8e;p=thirdparty%2Flinux.git drm/panel/himax-hx83102: 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.
