Subject: [PATCH 16/18] serial: pch: Don't initialize uart_port's spin_lock.
Origin: https://www.kernel.org/pub/linux/kernel/projects/rt/6.8/older/patches-6.8.2-rt11.tar.xz
There is no need to directly initialize the spinlock_t in struct
uart_port. The structure is later passed to uart_add_one_port() which
initialize the complete struct including the lock member.
Remove spin_lock_init() on uart_port's internal lock.
