The reverted commit makes the state machine only ever go from SRC_ATTACH_WAIT to SNK_TRY in endless loop when toggling. After revert it goes to SRC_ATTACHED after initially trying SNK_TRY earlier, as it should for toggling to ever detect the power source mode and the port is again able to provide power to attached power sinks.
This reverts commit 2d6d80127006ae3da26b1f21a65eccf957f2d1e5.
