Subject: [PATCH][next] net: axienet: Fix fall-through warning for Clang
Date: Fri, 28 May 2021 14:58:31 -0500	[thread overview]
Message-ID: <20210528195831.GA39131@embeddedor> (raw)

In preparation to enable -Wimplicit-fallthrough for Clang, fix multiple
warnings by explicitly adding a fallthrough statement instead of just
letting the code fall through to the next case.

Link: https://github.com/KSPP/linux/issues/115
Signed-off-by: Gustavo A. R. Silva <gustavoars@kernel.org>
---
JFYI: We had thousands of these sorts of warnings and now we are down
      to just 25 in linux-next. This is one of those last remaining
      warnings.
