The pattern rule `$(OUTPUT)/%: %.c` inadvertently included a circular dependency on the global-timer target due to its inclusion in $(TEST_GEN_PROGS_EXTENDED). This resulted in a circular dependency warning during the build process. To resolve this, the dependency on $(TEST_GEN_PROGS_EXTENDED) has been replaced with an explicit dependency on $(OUTPUT)/libatest.so. This change ensures that libatest.so is built before any other targets that require it, without creating a circular dependency. This fix addresses the following warning: make[4]: Entering directory 'tools/testing/selftests/alsa' make[4]: Circular default_modconfig/kselftest/alsa/global-timer <- default_modconfig/kselftest/alsa/global-timer dependency dropped. make[4]: Nothing to be done for 'all'. make[4]: Leaving directory 'tools/testing/selftests/alsa' Cc: Mark Brown <broonie@kernel.org> Cc: Jaroslav Kysela <perex@perex.cz> Cc: Takashi Iwai <tiwai@suse.com> Cc: Shuah Khan <shuah@kernel.org> Signed-off-by: Li Zhijian <lizhijian@fujitsu.com> Link: https://patch.msgid.link/20241218025931.914164-1-lizhijian@fujitsu.com Signed-off-by: Takashi Iwai <tiwai@suse.de>
