tty: n_gsm: fix sometimes uninitialized warning in gsm_dlci_modem_output() (2022-04-26 08:09:46 +0200)

TTY/Serial fixes for 5.18-rc5

Here are some small serial driver fixes, and a larger number of GSM line
discipline fixes for 5.18-rc5.

These include:
- lots of tiny n_gsm fixes for issues to resolve a number of
reported problems. Seems that people are starting to actually
use this code again.
- 8250 driver fixes for some devices
- imx serial driver fix
- amba-pl011 driver fix

All of these have been in linux-next for a while with no reported
