| |
3.2-stable review patch. If anyone has any objections, please let me know.
------------------
From: "K. Y. Srinivasan" <kys@microsoft.com>
commit 8f257a142fc3868d69de3f996b95d7bdbc509560 upstream.
The function vmbus_exists() was introduced recently to deal with cases where the vmbus driver failed to initialize and yet other Hyper-V drivers attempted to register with the vmbus bus driver. This patch introduced a bug where vmbus_driver_unregister() would fail to unregister the driver. This patch fixes the problem.
