Subject: [PATCH 0/2] serial: core: fix console port-lock regression
Date: Wed,  9 Sep 2020 16:30:59 +0200
Message-ID: <20200909143101.15389-1-johan@kernel.org> (raw)

These patches fix up the regressions introduced by the console-detach
changes after which the port lock was no longer initialised for not-yet
registered consoles during port registration or during early console
setup.

Some of the reported driver regressions have been addressed by patching
individual drivers and later by a work-around for the first issue in
core but the early setup issue remained.
