A commit adding back the stopping of tx on port shutdown failed to add back the locking which had also been removed by commit e83766334f96 ("tty: serial: qcom_geni_serial: No need to stop tx/rx on UART shutdown").
Holding the port lock is needed to serialise against the console code, which may update the interrupt enable register and access the port state.

I already reviewed this[1]. I suggest using b4 for automated tag pickup.
There were changes in v2 so I dropped your tag on purpose.
