I'm facing it again on the latest -rc4 and Clang 19 (the latest master Git):

drivers/gpu/drm/amd/amdgpu/../display/dc/dml2/display_mode_core.c:6710:12:
warning: stack frame size (2128) exceeds limit (2048) in
'dml_core_mode_support' [-Wframe-larger-than]
 6710 | dml_bool_t dml_core_mode_support(struct display_mode_lib_st
*mode_lib)
      |            ^
1 warning generated.

Please fix it once and forever somehow, don't abuse the stack =\

Thanks,
Olek
