Carlos Sanchez 6c1ead5e77 serial: MPSC: Remove race between Rx stop & restart ... The patch in commit ID f7232056bf stops (aborts) the MPSC's receive engine just before restarting it. Unfortunately, it doesn't wait for the abort to complete before restarting it which creates a race between the abort and the restart. If the restart occurs first, the in-progress abort stops it again and the rx engine remains stopped. Instead, do the abort when the SDMA engine is being stopped. Make sure to wait for the abort to complete before continuing. Signed-off-by: Carlos Sanchez <carlos.sanchez@gecoinc.com> Signed-off-by: Mark A.
