[PATCH 1/3] [mobile] simplify code to send events into GSM 3.22 code

This is merely a historical archive of years 2008-2021, before the migration to mailman3.

A maintained and still updated list archive can be found at https://lists.osmocom.org/hyperkitty/list/baseband-devel@lists.osmocom.org/.

instead of gsm322_msgb_alloc() followed by a sendmsg
with intermittent error checks we now have only a single
