  To: Mike Marciniszyn, Dennis Dalessandro, Doug Ledford, Jason Gunthorpe
  Cc: linux-rdma, linux-kernel, Gustavo A. R. Silva

Replace the existing /* fall through */ comments and its variants with
the new pseudo-keyword macro fallthrough[1]. Also, remove unnecessary
fall-through markings when it is the case.

[1] https://www.kernel.org/doc/html/v5.7-rc7/process/deprecated.html?highlight=fallthrough#implicit-switch-case-fall-through

Signed-off-by: Gustavo A. R. Silva <gustavoars@kernel.org>

Changes in v2:
 - Address fall-through markings in drivers/infiniband/hw/hfi1/chip.c
   in a separate patch[2].
