Subject: [PATCH] Revert "tty: serial: add missing spin_lock_init for SiFive
serial console"
This reverts commit 17b4efdf4e4867079012a48ca10d965fe9d68822.
There has been a quick fix against uninitialised lock revealed by
the commit f743061a85f5 ("serial: core: Initialise spin lock before use
in uart_configure_port()"). Since we have now better fix in serial core,
this may be safely reverted.
Fixes: 17b4efdf4e48 ("tty: serial: add missing spin_lock_init for SiFive serial console")
Depends-on: f743061a85f5 ("serial: core: Initialise spin lock before use in uart_configure_port()")
