[PATCH 4.2 088/110] md/raid1: submit_bio_wait() returns 0 on success

[Greg Kroah-Hartman]

4.2-stable review patch.  If anyone has any objections, please let me know.

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

From: Jes Sorensen <Jes.Sorensen@xxxxxxxxxx>

commit 203d27b0226a05202438ddb39ef0ef1acb14a759 upstream.

This was introduced with 9e882242c6193ae6f416f2d8d8db0d9126bd996b
which changed the return value of submit_bio_wait() to return != 0 on
error, but didn't update the caller accordingly.

Fixes: 9e882242c6 ("block: Add submit_bio_wait(), remove from md")
