Here is the big set of tty and serial driver patches for 5.10-rc1. Lots of little things in here, including: - tasklet_setup api conversions - sysrq support for capital letters - vt and vc cleanups and unwinding the mess some more - serial driver updates and minor tweaks - new device ids - rs485 support for some drivers - serial binding documentation updates - lots of small serial driver changes for reported issues All have been in linux-next for a while with no reported issues.
