So just a few seconds after sending this I remembered why I zapped it: it was a
Sparse failure reported by the kbuild-test robot.

Here's the report:

[tip:x86/urgent 14/14] drivers/infiniband/hw/hns/hns_roce_hw_v1.c:1690:22: sparse: incorrect type in argument 1 (different base types)

Since you were on Cc: of that report I assumed you'd take care of it.

Thanks,
