Subject: [PATCH v2 2/2] staging: lustre: restore initialization of return code
Date: Tue, 25 Oct 2016 23:22:31 +0200	[thread overview]
Message-ID: <20161025212310.2346367-2-arnd@arndb.de> (raw)
In-Reply-To: <20161025212310.2346367-1-arnd@arndb.de>

A recent rework removed the initialization of the successful return
code from lov_getstripe:

drivers/staging/lustre/lustre/lov/lov_pack.c: In function 'lov_getstripe':
drivers/staging/lustre/lustre/lov/lov_pack.c:426:9: error: 'rc' may be used uninitialized in this function [-Werror=maybe-uninitialized]
drivers/staging/lustre/lustre/lov/lov_pack.c:313:6: note: 'rc' was declared here

This adds it back.

Fixes: e10a431b3fd0 ("staging: lustre: lov: move LSM to LOV layer")
Signed-off-by: Arnd Bergmann <arnd@arndb.de>
