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

[Samuel Thibault]

Hello,

Just looking over the patch, it looks good. I don't think it needs to be
split in 4 pieces though, I'd say merge patches 1, 3, and 4 together,
where patch 3 would be modified to make dummy use spk_serial_out too, to
get a patch which does just one complete thing: make serial_out a
method.

Then you'll have other patches introducing spk_serial_out_tty and making
some drivers use it.

Also note that as Greg said, the patches you have just submitted do
not really make sense alone.  I don't know if staging people feel like
applying them while it's only pavement for future work.  If so, then
good; otherwise, then fine too: it's good that you have sent them so
that we could check how they look like, I just wanted to let you know
that they might not get applied yet, just because one may want to see
the future patches before applying what you have done so far.

BTW, I have been looking at functions again, we'll also need
a spk_synth_immediate_tty that drivers can use instead of
spk_synth_immediate, in addition to the _in, and _out functions. For now
(i.e. to make the dummy driver work, and probably a few simple more),
the tty versions for _out and _synth_immediate will probably enough to
get something working and commitable to the main kernel.

Also, as mentioned, now the hard work is getting to open the tty from
the kernel :) That'd be in a spk_tty_synth_probe function that drivers
would use instead of spk_serial_synth_probe.
