Subject: RISC-V: KVM: Exit run-loop immediately if xfer_to_guest fails
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=af934432e4a169f7252a114a6c5c7289366bd0ab;p=users%2Fjedix%2Flinux-maple.git

RISC-V: KVM: Exit run-loop immediately if xfer_to_guest fails

If xfer_to_guest_mode_handle_work() fails in the run-loop then exit
the run-loop immediately instead of doing it after some more work.
