Subject: [PATCH][next] gpio: ath79: Fix fall-through warning for Clang
Date: Thu, 19 Nov 2020 11:09:01 -0600 [thread overview]
Message-ID: <20201119170901.GA22703@embeddedor> (raw)
In preparation to enable -Wimplicit-fallthrough for Clang, fix a
warning by explicitly adding a fallthrough pseudo-keyword to indicate
that the code is intended to fall through to the next case.
