Michael Ellerman eeb3f0b0c3 selftests/gpio: Fix build when source tree is read only ... [ Upstream commit b68c1c65de ] Currently the gpio selftests fail to build if the source tree is read only: make -j 160 -C tools/testing/selftests TARGETS=gpio make[1]: Entering directory '/linux/tools/testing/selftests/gpio' make OUTPUT=/linux/tools/gpio/ -C /linux/tools/gpio make[2]: Entering directory '/linux/tools/gpio' mkdir -p /linux/tools/gpio/include/linux 2>&1 || true ln -sf /linux/tools/gpio/../../include/uapi/linux/gpio.h /linux/tools/gpio/include/linux/gpio.h ln: failed to create symbolic link '/linux/tools/gpio/include/linux/gpio.h': Read-only file system This happens because we ask make to build ../../../gpio (tools/gpio) without pointing OUTPUT away from the source directory. To fix it we create a subdirectory of the existing OUTPUT directory, called tools-gpio, and tell tools/gpio to build in there.
