Y. Srinivasan" 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. Signed-off-by: K. Y.
