Subject: [PATCH] Input: libps2 - mark expected switch fall-through
Date: Tue, 7 May 2019 13:24:09 -0500	[thread overview]
Message-ID: <20190507182409.GA11027@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/input/serio/libps2.c: In function ‘ps2_handle_ack’:
drivers/input/serio/libps2.c:407:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
   if (ps2dev->flags & PS2_FLAG_NAK) {
      ^
drivers/input/serio/libps2.c:417:2: note: here
  case 0x00:
  ^~~~

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

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