Subject: Drivers: hv: vmbus: Cleanup vmbus_establish_gpadl()
From: "K. Y. Srinivasan" <kys@xxxxxxxxxxxxx>
commit 72c6b71c245dac8f371167d97ef471b367d0b66b upstream.
Eliminate the call to BUG_ON() by waiting for the host to respond. We are
trying to reclaim the ownership of memory that was given to the host and so
we will have to wait until the host responds.
