The KUnit test for cirrus_scodec uses GPIO library functions so select GPIOLIB in Kconfig. This fixes the ld failures on builds that didn't already select GPIOLIB. ld: vmlinux.o: in function `cirrus_scodec_test_gpio_get': sound/pci/hda/cirrus_scodec_test.c:40: undefined reference to `gpiochip_get_data' ld: vmlinux.o: in function `cirrus_scodec_test_gpio_probe': sound/pci/hda/cirrus_scodec_test.c:94: undefined reference to `gpiochip_generic_request' ld: sound/pci/hda/cirrus_scodec_test.c:94: undefined reference to `gpiochip_generic_free' ld: sound/pci/hda/cirrus_scodec_test.c:95: undefined reference to `devm_gpiochip_add_data_with_key' Signed-off-by: Richard Fitzgerald <rf@xxxxxxxxxxxxxxxxxxxxx> Reported-by: kernel test robot <lkp@xxxxxxxxx> Closes: https://lore.kernel.org/oe-kbuild-all/202309201646.NnjfKPWk-lkp@xxxxxxxxx/ Fixes: 2144833e7b41 ("ALSA: hda: cirrus_scodec: Add KUnit test") --- sound/pci/hda/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/sound/pci/hda/Kconfig b/sound/pci/hda/Kconfig index 706cdc589e6f..21a90b3c4cc7 100644 --- a/sound/pci/hda/Kconfig +++ b/sound/pci/hda/Kconfig @@ -97,6 +97,7 @@ config SND_HDA_CIRRUS_SCODEC config SND_HDA_CIRRUS_SCODEC_KUNIT_TEST tristate "KUnit test for Cirrus side-codec library" if !KUNIT_ALL_TESTS select SND_HDA_CIRRUS_SCODEC + select GPIOLIB depends on KUNIT default KUNIT_ALL_TESTS help -- 2.30.2
