Hi Krzysztof,
It's based on a randconfig with compile_test without gpiolib.
I reproduced it with make defconfig followed by selecting
x86_32
SPI
SND_SOC_SAMSUNG
MFD_ARIZONA_I2C
MFD_ARIZONA
SND_SOC
COMPILE_TEST
X86_INTEL_QUARK
COMMON_CLK
SND_SOC_SAMSUNG
SND_SOC_SAMSUNG_TM2_WM5110
Here's another patch solving the same problem with complete explanation:
Commit 638f958baeaf
("extcon: Allow compile test of GPIO consumers if !GPIOLIB")
as you're suggesting, we could add depend on GPIOLIB.
extcon has the following: depends on GPIOLIB || COMPILE_TEST
smartq_wm8987.c also has gpio_consumer.h for SND_SOC_SMARTQ
which would give the following update on samsung/Kconfig besides initial patch:
