Subject: [PATCH] iw_cxgb4: Fix error return code in c4iw_rdev_open()
Date: Sat, 17 Sep 2016 00:41:37 +0000	[thread overview]
Message-ID: <1474072897-30502-1-git-send-email-weiyj.lk@gmail.com> (raw)

From: Wei Yongjun <weiyongjun1-hv44wF8Li93QT0dZR+AlfA@public.gmane.org>

Fix to return error code -ENOMEM from the __get_free_page() error
handling case instead of 0, as done elsewhere in this function.

Fixes: 05eb23893c2c ("cxgb4/iw_cxgb4: Doorbell Drop Avoidance Bug Fixes")
