There was a bug in this function where the bit for host_command was being set in the ec_status variable. This caused the ALERT# GPIO line to be held low which in turn caused the EC MCU to loop and keep reading the ALERT register. BUG=none BRANCH=none TEST=manual Tested against Zinger in both ports and Zinger and Samus at connected into each port. Verified that it established a PD contract for both ports and that the alert line was no longer being held low Change-Id: I5540440a68581521eb002411f728a4eac2f22caf Signed-off-by: Scott Collyer <scollyer@chromium.org> Reviewed-on: https://chromium-review.googlesource.com/288252 Reviewed-by: Alec Berg <alecaberg@chromium.org> Commit-Queue: Alec Berg <alecaberg@chromium.org> Tested-by: Alec Berg <alecaberg@chromium.org>
