The arm64 clang-14 allmodconfig failed on stable-rc 5.19. This build failure got fixed on the mainline tree two weeks ago.

ASoC: Intel: avs: Use lookup table to create modules
As reported by Nathan, when building avs driver using clang with: CONFIG_COMPILE_TEST=y CONFIG_FORTIFY_SOURCE=y CONFIG_KASAN=y CONFIG_PCI=y CONFIG_SOUND=y CONFIG_SND=y CONFIG_SND_SOC=y CONFIG_SND_SOC_INTEL_AVS=y
there are reports of too big stack use, like: sound/soc/intel/avs/path.c:815:18: error: stack frame size (2176) exceeds limit (2048) in 'avs_path_create' [-Werror,-Wframe-larger-than] struct avs_path *avs_path_create(struct avs_dev *adev, u32 dma_id, ^ 1 error generated.
This is apparently caused by inlining many calls to guid_equal which inlines fortified memcpy, using 2 size_t variables.
Instead of hardcoding many calls to guid_equal, use lookup table with one call, this improves stack usage.
