From f3df05c805983427319eddc2411a2105ee1757cf Mon Sep 17 00:00:00 2001 From: Matt Flax 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.
