+       Fix race condition introduced in rev 1.189; after the change, if there
+       is THRE interrupt occurs between the LSR read and IIR read, we won't
+       see the LSR_TXRDY bit when testing it in the variable `lsr' and we
+       don't interrupted again (as the corresponding bit in the IIR is
+       cleared by reading, except for some broken device).
+       Tested by Matthias Scheler and me, reviewed by Allen Briggs.
+       Closes PR#25010.
