Subject: [PATCH net-next] wimax/i2400m/control: Mark expected switch fall-through
Date: Wed, 24 Apr 2019 11:20:16 -0500 [thread overview]
Message-ID: <20190424162016.GA8393@embeddedor> (raw)
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.
This patch fixes the following warning:
In file included from drivers/net/wimax/i2400m/debug-levels.h:30,
from drivers/net/wimax/i2400m/control.c:86:
drivers/net/wimax/i2400m/control.c: In function ‘i2400m_report_tlv_system_state’:
./include/linux/wimax/debug.h:200:4: warning: this statement may fall through [-Wimplicit-fallthrough=]

^~~~~~~~
drivers/net/wimax/i2400m/control.c:355:2: note: here
case I2400M_SS_DISCONNECTING:
^~~~
Warning level 3 was used: -Wimplicit-fallthrough=3
This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.
