[PATCH 3.17 018/319] cxgb4 : Fix missing initialization of win0_lock

From: Greg Kroah-Hartman
Date: Tue Nov 11 2014 - 20:20:19 EST


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

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

From: Anish Bhatt <anish@xxxxxxxxxxx>

[ Upstream commit e327c225c911529898ec300cb96d2088893de3df ]

win0_lock was being used un-initialized, resulting in warning traces
being seen when lock debugging is enabled (and just wrong)

Fixes : fc5ab0209650 ('cxgb4: Replaced the backdoor mechanism to access the HW
memory with PCIe Window method')
