Subject: [PATCH 4.9 108/138] adm80211: return an error if adm8211_alloc_rings() fails

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

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

From: Dan Carpenter <dan.carpenter@...cle.com>


[ Upstream commit c705a6b3aa7804d7bc6660183f51e510c61dc807 ]

We accidentally return success when adm8211_alloc_rings() fails but we
should preserve the error code.

Fixes: cc0b88cf5ecf ("[PATCH] Add adm8211 802.11b wireless driver")
