Summary
serial: 8250: Fix oops for port->pm on uart_change_pm()
Details

In the Linux kernel, the following vulnerability has been resolved:

serial: 8250: Fix oops for port->pm on uartchangepm()

Unloading a hardware specific 8250 driver can produce error "Unable to handle kernel paging request at virtual address" about ten seconds after unloading the driver. This happens on uarthangup() calling uartchange_pm().

Turns out commit 04e82793f068 ("serial: 8250: Reinit port->pm on port specific driver unbind") was only a partial fix. If the hardware specific driver has initialized port->pm function, we need to clear port->pm too. Just reinitializing port->ops does not do this. Otherwise serial8250pm() will call port->pm() instead of serial8250do_pm().
