Subject: [PATCH RESEND][next] rtl8xxxu: Fix fall-through warnings for Clang
Date: Fri, 5 Mar 2021 03:48:50 -0600 [thread overview]
Message-ID: <20210305094850.GA141221@embeddedor> (raw)
In preparation to enable -Wimplicit-fallthrough for Clang, fix
multiple warnings by replacing /* fall through */ comments with
the new pseudo-keyword macro fallthrough; instead of letting the
code fall through to the next case.
Notice that Clang doesn't recognize /* fall through */ comments as
implicit fall-through markings.
