Linux 5.15-rc3

Hi,

with CONFIG_INFINIBAND_QIB=m I observe a build-error since Linux
v5.13-rc1 release.
This is with LLVM/Clang >= v13.0.0-rc3 on my Debian/unstable AMD64 system.

For details see ClangBuiltLinux issue #1452 (see [1]).

The fix is pending in rdma.git#for-rc (see [2]):

commit  3110b942d36b961858664486d72f815d78c956c3
"IB/qib: Fix clang confusion of NULL pointer comparison"

Dunno if there was a pull-request from linux-rdma folks.
Cannot say if it is worth taking this directly...?

Just want to let you know.

Regards,

P.S.: My kernel-config is attached.
