Subject: [PATCH AUTOSEL 4.19 01/34] ASoC : cs4265 : readable register too low
From: Matt Flax <flatmax@...tmax.org>
[ Upstream commit f3df05c805983427319eddc2411a2105ee1757cf ]
The cs4265_readable_register function stopped short of the maximum
register.
An example bug is taken from :
https://github.com/Audio-Injector/Ultra/issues/25
Where alsactl store fails with :
Cannot read control '2,0,0,C Data Buffer,0': Input/output error
This patch fixes the bug by setting the cs4265 to have readable
registers up to the maximum hardware register CS4265_MAX_REGISTER.
