Subject: [PATCH 3.16 181/305] sysv: return 'err' instead of 0 in

------------------

From: YueHaibing <yuehaibing@...wei.com>

commit c4b7d1ba7d263b74bb72e9325262a67139605cde upstream.

Fixes gcc '-Wunused-but-set-variable' warning:

fs/sysv/inode.c: In function '__sysv_write_inode':
fs/sysv/inode.c:239:6: warning:
 variable 'err' set but not used [-Wunused-but-set-variable]

__sysv_write_inode should return 'err' instead of 0

Fixes: 05459ca81ac3 ("repair sysv_write_inode(), switch sysv to simple_fsync()")
