From 8f257a142fc3868d69de3f996b95d7bdbc509560 Mon Sep 17 00:00:00 2001 From: "K. Y. Srinivasan" Date: Tue, 27 Dec 2011 13:49:37 -0800 Subject: [PATCH] Drivers:hv: Fix a bug in vmbus_driver_unregister() 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. Signed-off-by: K. Y.
