  serial: exar: Fix GPIO configuration for Sealevel cards based on XR17V35X (2020-07-24 10:58:14 +0200)

TTY/Serial/fbcon fixes for 5.8-rc7

Here are some small tty and serial and fbcon fixes for 5.8-rc7 to
resolve some reported issues.

The fbcon fix is in here as it was simpler to take it this way (and it
was acked by the maintainer) as it was related to the vt console fix as
well, both of which resolve syzbot-found issues in the console handling
code.

The other serial driver fixes are for small issues reported in the -rc
releases.

All of these have been in linux-next with no reported issues.
