Subject: [PATCH 0/4] serial: core: fix up sysrq regressions
Date: Tue,  2 Jun 2020 16:00:54 +0200	[thread overview]
Message-ID: <20200602140058.3656-1-johan@kernel.org> (raw)

This series fixes a few regressions introduced by the recent sysrq
rework that went into 5.6.

The port unlock fix is tagged for stable, and the fix for the
unnecessary per-character overhead probably could be as well although
it is a bit more intrusive.
