[GIT PULL] printk for 5.10 (includes lockless ringbuffer)

Linus,

please pull a printk hotfix from

git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux.git tags/printk-for-5.10-rc6-fixup

=========================

- Do not lose trailing newline in pr_cont() calls.

- Two trivial fixes: dead-store and a config description.

=========================

PS: I do not have much experience with pushing fixes this late
in the release cycle.

I push the important fix even before it has reached linux-next.
The fix is straightforward and trivial. And it looks better to have
it in rc6 than in the potentially last one rc7.

Also I added the two trivial fixes that I queued few weeks ago.
They were trivial enough to get pushed at any time. And they
fixed something that was introduced in 5.10-rc1.

Feel free to postpone this for rc7 or take only the one fix
of the newlines handling.
