Subject: [PATCH v4 02/12] Revert "kgdboc: disable the console lock when in kgdb"

Message-ID: <20200507130644.v4.2.I02258eee1497e55bcbe8dc477de90369c7c7c2c5@changeid> (raw)
In-Reply-To: <20200507200850.60646-1-dianders@chromium.org>
This reverts commit 81eaadcae81b4c1bf01649a3053d1f54e2d81cf1.
Commit 81eaadcae81b ("kgdboc: disable the console lock when in kgdb")
is no longer needed now that we have the patch ("kgdb: Disable
WARN_CONSOLE_UNLOCKED for all kgdb"). Revert it.
