$ make -skj"$(nproc)" ARCH=loongarch LLVM=1 clean allmodconfig drivers/media/platform/rockchip/rkvdec/rkvdec-vdpu383-h264.o
drivers/media/platform/rockchip/rkvdec/rkvdec-vdpu383-h264.c:485:12: error: stack frame size (2064) exceeds limit (2048) in 'rkvdec_h264_run' [-Werror,-Wframe-larger-than]

There have been other instances of -Wframe-larger-than in this driver:

https://lore.kernel.org/20260202094804.1231706-1-arnd@kernel.org/
https://lore.kernel.org/20260202094804.1231706-2-arnd@kernel.org/

and the maintainers have said they want to rework it:

So I will disable this driver in CI for ARCH=loongarch allmodconfig and we will see where those developments go before attempting to workaround this in another way.
