Subject: [PATCH v3 02/11] Revert "kgdboc: disable the console lock when in kgdb"

Message-ID: <20200428141218.v3.2.I02258eee1497e55bcbe8dc477de90369c7c7c2c5@changeid> (raw)
In-Reply-To: <20200428211351.85055-1-dianders@chromium.org>

Commit 81eaadcae81b ("kgdboc: disable the console lock when in kgdb")
is no longer needed now that we have the patch ("kgdb: Disable
