Hi Starovoitov, This one does have the issue you mentioned. [PATCH 2/4] selftests/gpio: fix paths in Makefile
And can be fixed by: --- a/tools/testing/selftests/gpio/Makefile +++ b/tools/testing/selftests/gpio/Makefile @@ -1,5 +1,6 @@ # SPDX-License-Identifier: GPL-2.0 +OUTPUT ?= $(shell pwd) TEST_PROGS := gpio-mockup.sh TEST_FILES := gpio-mockup-sysfs.sh $(BINARIES) BINARIES := gpio-mockup-chardev @@ -24,7 +25,7 @@ LDLIBS += -lmount -I/usr/include/libmount $(BINARIES): gpio-utils.o ../../../../usr/include/linux/gpio.h gpio-utils.o: - make ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) -C ../../../gpio + make ARCH=$(ARCH) CROSS_COMPILE=$(CROSS_COMPILE) OUTPUT=$(OUTPUT)/ -C ../../../gpio ../../../../usr/include/linux/gpio.h: I will update it later.
