-Wstringop-overflow is broken on GCC11. In future changes it will be moved to the normal C flags in the top level Makefile (out of Makefile.extrawarn), but accounting for the compiler support. Just remove it out of i915's forced extra warnings, preparing for the upcoming change and avoiding build warnings to show up. Fixes:2250c7ead8("drm/i915: enable W=1 warnings by default") References: https://lore.kernel.org/all/45ad1d0f-a10f-483e-848a-76a30252edbe@paulmck-laptop/ Signed-off-by: Lucas De Marchi <lucas.demarchi@intel.com> Reviewed-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20240112154912.1775199-1-lucas.demarchi@intel.com (cherry picked from commit05ae67d95b) Signed-off-by: Joonas Lahtinen <joonas.lahtinen@linux.intel.com>
