From 804e73adf5cf4b3aea3b6ce058f4dc0191143821 Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 22 Aug 2017 07:44:52 +0200 Subject: ASoC: rt5670: Fix GPIO headset detection regression RT5670 codec driver and its machine driver for Intel CHT assume the implicit GPIO mapping on the index 0 while BIOS on most devices don't provide it. The recent commit f10e4bf6632b ("gpio: acpi: Even more tighten up ACPI GPIO lookups") restricts such cases and it resulted in a regression where the headset jack setup fails like: rt5670 i2c-10EC5672:00: ASoC: Cannot get gpio at index 0: -2 rt5670 i2c-10EC5672:00: Adding jack GPIO failed For fixing this, we need to provide the GPIO mapping explicitly in the machine driver. Also this patch corrects the string to be passed to gpiolib to match with the pre-given mapping, too.

This can not be changed, as it is a backwards compatibility measure itself. We can not rely on the return value of this function alone, but must check if the card name has been filled sucessfully when deciding to skip the fallback path, which is in place for existing users.
