[PATCH 0/3]: staging: speakup: refactor to make room for serial comms changes

[Okash Khawaja]

Hi,

Following set of patches introduces serial_out() method which will point to
spk_serial_out() for other drivers and spk_serial_out2() for speakup_dummy.
Intention is to allow changing implementation of serial_out() for
speakup_dummy while allowing other drivers to continue unaffected.

Thanks,
Okash
