the commit f10e4bf6632b5be11cea875b66ba959833a69258
gpio: acpi: Even more tighten up ACPI GPIO lookups
now generates the following issue
[ 9.694204] rt5670 i2c-10EC5672:00: ASoC: Cannot get gpio at index 0: -2
[ 9.694293] rt5670 i2c-10EC5672:00: Adding jack GPIO failed
This is the 3rd occurrence of an audio issue with this commit [1][2],
what is the recommended fix here since this codec is not only used in
ACPI-based devices and do we need to check for more issues in audio
drivers?
Likely you need to give the proper mapping in the machine driver, and
correct the hp_gpio.name to the corresponding one.
It's cht_bsw_rt5672? If so, the required change would be something
like below.
yep, this works, thanks Takashi. With an additional DMI fix i'll submit
later I get sound on the Dell 5585.
