patching struct uart_port seems a bit overhead. After reading the code
again, I propose another solution, similar as what dl_write() is used
in
8250 core:
1.introduce the hook to struct uart_8250_port as my previous patches
do,
2.rename current serial8250_set_divisor() as
default_serial_get_divisor()
then introduce a new serial8250_set_divisor() as:
static inline void serial8250_set_divisor(struct uart_8250_port
*up,....)
{
up->set_divisor();
}
and point up->set-divisor to default_serial_get_divisor
what do you think about this solution?Disagree. See my previous answer for details. -- Andy Shevchenko [off-list ref] Intel Finland Oy
