[PATCH v3 0/9] serial: qcom-geni: fix receiver enable

[Johan Hovold]

This series is a follow up to the console fixes in 6.12-rc1 that can
interact badly with some pre-existing bugs.

Specifically, the receiver could end up being disabled when
set_termios() races with the console code during boot. This can manifest
itself as a serial getty not accepting input.

Fixing the missing locking in set_termios() exposes another
long-standing bug in the DMA implementation (e.g. used for Bluetooth),
which is also fixed.
