Subject: Revert "mux: fix ctrl-a b again"

Revert "mux: fix ctrl-a b again"

This reverts commit 1b2503fcf7b5932c5a3779ca2ceb92bd403c4ee7.

Unfortunately this fix regresses console handling on MIPS Malta;
since the mux ctrl-a b bug is not a regression since 2.11, we
take the conservative approach and just drop it from 2.12.
