[PATCH 3.12 104/142] Drivers: hv: vmbus: Don't wait after requesting offers

[Jiri Slaby]

From: "K. Y. Srinivasan" <kys@xxxxxxxxxxxxx>

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

===============

commit 73cffdb65e679b98893f484063462c045adcf212 upstream.

Don't wait after sending request for offers to the host. This wait is
unnecessary and simply adds 5 seconds to the boot time.
