From: Anusha Srivatsa Date: Fri, 11 Jul 2025 04:31:25 +0000 (-0500) Subject: drm/panel/boe-himax8279d: Use refcounted allocation in place of devm_kzalloc() X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=d27da6792c805f5b4d88f21e8ba2069b1f2d41ea;p=thirdparty%2Flinux.git drm/panel/boe-himax8279d: 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.
