Subject: [PATCH 3/3] ASoC: mt6358: Remove undefined HPx Mux enumeration values
Date: Sun, 26 Feb 2023 12:47:58 +0000 [thread overview]
Message-ID: <20230224-asoc-mt6358-quick-fixes-v1-3-747d9186be4b@kernel.org> (raw)
In-Reply-To: <20230224-asoc-mt6358-quick-fixes-v1-0-747d9186be4b@kernel.org>
The HPx Mux enumerations define values 5, 6 and 7 but describe them as
"undefined" and map them to the value 0 on writing. Given the descriptions
and behaviour it seems that these values are invalid and should not be
present in the register, the current behaviour is detected as problematic
by mixer-test:
# # HPL Mux.0 expected 5 but read 0, is_volatile 0
# # HPL Mux.0 expected 6 but read 0, is_volatile 0
# # HPL Mux.0 expected 7 but read 0, is_volatile 0
Remove the values from the enumeration, this will prevent userspace setting
them.
