Subject: [PATCH] usb: phy: Use fallthrough pseudo-keyword
Date: Tue, 7 Jul 2020 15:00:40 -0500 [thread overview]
Message-ID: <20200707200040.GA4525@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.
