From: Matt Flax flatmax@flatmax.org Date: Wed, 8 May 2019 16:33:13 +1000 Subject: [PATCH] ASoC : cs4265 : readable register too low
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.
