From: "K. Y. Srinivasan" <kys@xxxxxxxxxxxxx>
3.4.109-rc1 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.
