Alex,
This is the third report of linux-next being broken for clang due to the
AMDGPU tree.
1. https://lore.kernel.org/lkml/20230522171557.32027acf@canb.auug.org.au/
2. https://lore.kernel.org/lkml/20230522171145.38a8bd4d@canb.auug.org.au/
3. https://lore.kernel.org/lkml/20230522170031.5fb87a64@canb.auug.org.au/

Our CI is red as a result.

When will AMD start testing their kernels with Clang?
