From f1f02fa4f15bc682814c71fe05c6b76e5f5fba80 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Uwe=20Kleine-K=C3=B6nig?= Date: Thu, 7 Aug 2014 23:48:25 +0200 Subject: [PATCH] net: ucc_geth: make probe consistently acquire a reference to the phy node MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit When the driver attaches to a device that has a phy handle the probe routine returns with a reference to that node. This reference is correctly dropped in the error path and the remove function. In the fixed phy case however no reference is acquired and so the error path might drop a reference the driver isn't holding. Fix that by getting a reference to the MAC.
