| parent | serial: pch: Don't initialize uart_port's spin_lock. (diff) | |
serial: pch: Remove eg20t_port::lock.
The struct eg20t_port has a spinlock_t which is used for locking while
access I/O of the device. Then there is the uart_portlock which is
sometimes and nests within eg20t_port's lock.
The uart_port lock is not used while using the struct in
pch_uart_hal_read() which might be okay. Then both locks are used in
pch_console_write() which looks odd especially the double try_lock part.
All in all it looks like the uart_port's lock could replace eg20t_port's
lock and simplify the code.
Remove eg20t_port::lock and use uart_port's lock for the lock scope.
