Nobody took the chance to fix (or at least localize) the warnings since
commit f0be87c42cbd (gcc-12: disable '-Warray-bounds' universally for
now). The new compiler (gcc-13) still reports issues like:
drivers/gpu/drm/amd/display/dc/core/dc_stream.c: In function 'dc_stream_remove_writeback':
drivers/gpu/drm/amd/display/dc/core/dc_stream.c:531:55: error: array subscript -1 is below array bounds of 'struct dc_writeback_info[1]' [-Werror=array-bounds]
Note that 'j' can never be negative. So disable the warning on gcc-13
too until someone takes time to localize them.
