Subject[PATCH] tmpfs: fix uninitialized return value in shmem_link
From: Darrick J. Wong <darrick.wong@oracle.com>

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: "tmpfs: fix link accounting when a tmpfile is linked in"
