[PATCH v2 0/4] staging: speakup: refactor to make room for serial comms changes

[Okash Khawaja]

Hi,

This set of patches introduces serial_out() method which will point to
spk_serial_out() for other drivers and spk_serial_out_tty() for speakup_dummy.
Intention is to allow changing implementation of serial_out() for speakup_dummy
while allowing other drivers to continue unaffected. spk_serial_out_tty() will
use tty_struct instance instead of outb.

Thanks,
Okash
