Subject: [PATCH] net: ehea: Mark expected switch fall-through
Date: Sun, 28 Jul 2019 19:30:09 -0500 [thread overview]
Message-ID: <20190729003009.GA25425@embeddedor> (raw)
Mark switch cases where we are expecting to fall through.
This patch fixes the following warning:
drivers/net/ethernet/ibm/ehea/ehea_main.c: In function 'ehea_mem_notifier':
include/linux/printk.h:311:2: warning: this statement may fall through [-Wimplicit-fallthrough=]
printk(KERN_INFO pr_fmt(fmt), ##__VA_ARGS__)
^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
drivers/net/ethernet/ibm/ehea/ehea_main.c:3253:3: note: in expansion of macro 'pr_info'
pr_info("memory offlining canceled");
^~~~~~~
drivers/net/ethernet/ibm/ehea/ehea_main.c:3256:2: note: here
case MEM_ONLINE:
^~~~
Notice that, in this particular case, the code comment is
modified in accordance with what GCC is expecting to find.
