[ Upstream commit f5d5510e7389fa264337fb524346bac9eb93adc8 ]

After merging the f2fs tree, today's linux-next build
(x86_64_allmodconfig) produced this warning:

In file included from fs/f2fs/dir.c:11:
fs/f2fs/f2fs.h: In function '__mark_inode_dirty_flag':
fs/f2fs/f2fs.h:2388:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
if (set)
^
fs/f2fs/f2fs.h:2390:2: note: here
case FI_DATA_EXIST:
^~~~

Exposed by my use of -Wimplicit-fallthrough
