From c9b4e8545ea302da9490ce34027c28816f8c0d0f Mon Sep 17 00:00:00 2001 From: Shuah Khan Date: Wed, 13 Nov 2019 20:43:41 +0800 Subject: [PATCH] tools: gpio: Use !building_out_of_srctree to determine srctree commit 4a6a6f5c4aeedb72db871d60bfcca89835f317aa upstream. make TARGETS=gpio kselftest fails with: Makefile:23: tools/build/Makefile.include: No such file or directory When the gpio tool make is invoked from tools Makefile, srctree is cleared and the current logic check for srctree equals to empty string to determine srctree location from CURDIR. When the build in invoked from selftests/gpio Makefile, the srctree is set to "." and the same logic used for srctree equals to empty is needed to determine srctree. Check building_out_of_srctree undefined as the condition for both cases to fix "make TARGETS=gpio kselftest" build failure.
