Alex,
This is the third report of linux-next being broken for clang due to the
AMDGPU tree.
1. https://lore.kernel.org/lkml/[email-masked]/
2. https://lore.kernel.org/lkml/[email-masked]/
3. https://lore.kernel.org/lkml/[email-masked]/

Our CI is red as a result.

When will AMD start testing their kernels with Clang?
