Subject: [PATCH] Bluetooth: Use fallthrough pseudo-keyword
Date: Wed, 8 Jul 2020 15:26:50 -0500	[thread overview]
Message-ID: <20200708202650.GA3866@embeddedor> (raw)

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.
