Subject: [PATCH] mmc: Annotate implicit fall through in jz_mmc_irq_worker
Date: Wed, 16 Jan 2019 20:52:19 +0100	[thread overview]
Message-ID: <20190116195219.2897-1-malat@debian.org> (raw)

There is a plan to build the kernel with -Wimplicit-fallthrough and
these places in the code produced warnings (W=1).

This commit removes the following warnings:

  drivers/mmc/host/jz4740_mmc.c:745:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
  drivers/mmc/host/jz4740_mmc.c:779:3: warning: this statement may fall through [-Wimplicit-fallthrough=]
