Hello,

I have warnings like this for mlx5 drivers on Ubuntu 22.04 with clang:

Message: Disabling mlx5 [drivers/net/mlx5]: missing internal dependency 
"common_mlx5"

Build command:
CC=clang PKG_CONFIG_PATH=/opt/rdma-core/build/lib/pkgconfig meson 
--werror --buildtype=debugoptimized build

gcc does not reproduce.

Regards,
Ali
