3.16.66-rc1 review patch. If anyone has any objections, please let me know.
------------------
From: "Darrick J. Wong" <darrick.w...@oracle.com>
commit 29b00e609960ae0fcff382f4c7079dd0874a5311 upstream.
When we made the shmem_reserve_inode call in shmem_link conditional, we
forgot to update the declaration for ret so that it always has a known
value. Dan Carpenter pointed out this deficiency in the original patch.
Fixes: 1062af920c07 ("tmpfs: fix link accounting when a tmpfile is linked in")
