Subject: [patch 2/7] staging: speakup: spk_serial_out and spk_wait_for_xmitr to take synth arg
Date: Mon, 13 Mar 2017 22:05:53 +0000 [thread overview]
Message-ID: <20170313220928.208561655@gmail.com> (raw)

[-- Attachment #1: 02_spk_serial_out_and_xmitr_to_take_synth --]
[-- Type: text/plain, Size: 8461 bytes --]
These two functions are always called from a context where spk_synth instance
is available. They also use the spk_synth instance but instead of taking it
as an argument, they rely on a global spk_synth instance inside synth.c which
points to the same synth as the one being passed in as argument.
