Subject: [PATCH net-next] net: dsa: microchip: mark expected switch fall-through
Date: Mon, 1 Apr 2019 15:34:49 -0500	[thread overview]
Message-ID: <20190401203448.GA5056@embeddedor> (raw)

In preparation to enabling -Wimplicit-fallthrough, mark switch cases
where we are expecting to fall through.

This patch fixes the following warning:

drivers/net/dsa/microchip/ksz9477.c: In function ‘ksz9477_get_interface’:
drivers/net/dsa/microchip/ksz9477.c:1145:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
   if (gbit)
      ^
drivers/net/dsa/microchip/ksz9477.c:1147:2: note: here
  case 0:
  ^~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
