serial: core: Initialise spin lock before use in uart_configure_port() (2020-07-10 14:44:46 +0200)
---------------------------------------------------------------- TTY/Serial driver fixes for 5.8-rc6
Here are some small tty and serial driver fixes for 5.8-rc6.
The largest set of patches in here is a revert of the sysrq changes that went into 5.8-rc1 but turned out to cause a noticable overhead and cpu usage.
Other than that, there's a few small serial driver fixes to resolve reported issues, and finally resolving the spinlock init problem on many serial driver consoles.
All of these have been in linux-next for a while with no reported issues.
