[PATCH 1/1] Drivers: hv: vmbus: Fix a bug in the handling of channel offers

From: K. Y. Srinivasan
Date: Mon Aug 26 2013 - 16:28:41 EST


The channel state should be correctly set before registering the device. In the current
code the driver probe would fail for channels that have been rescinded and subsequently
re-offered. Fix the bug.
