Subject: sysv: return 'err' instead of 0 in __sysv_write_inode
X-Git-Tag: v3.18.130~29
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b8115cdf32d41de013296e54d58e1b2ca81f35e2;p=thirdparty%2Fkernel%2Fstable.git

sysv: return 'err' instead of 0 in __sysv_write_inode

[ Upstream commit c4b7d1ba7d263b74bb72e9325262a67139605cde ]

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()")
