[PATCH 0/4] serial: core: fix up sysrq regressions

[Johan Hovold]

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.
