Drop HOSTAUDIO since it is now equivalent to UML_SOUND. Allow SOUND with UML regardless of HAS_IOMEM. Otherwise there is a kconfig warning for unmet dependencies. (This was not an issue when SOUND was defined in arch/um/drivers/Kconfig. I have done 50 randconfig builds and didn't find any issues.) This fixes build errors when CONFIG_SOUND is not set: ld: arch/um/drivers/hostaudio_kern.o: in function `hostaudio_cleanup_module': hostaudio_kern.c:(.exit.text+0xa): undefined reference to `unregister_sound_mixer' ld: hostaudio_kern.c:(.exit.text+0x15): undefined reference to `unregister_sound_dsp' ld: arch/um/drivers/hostaudio_kern.o: in function `hostaudio_init_module': hostaudio_kern.c:(.init.text+0x19): undefined reference to `register_sound_dsp' ld: hostaudio_kern.c:(.init.text+0x31): undefined reference to `register_sound_mixer' ld: hostaudio_kern.c:(.init.text+0x49): undefined reference to `unregister_sound_dsp' and this kconfig warning: WARNING: unmet direct dependencies detected for SOUND Fixes: 1da177e4c3f4 ("Linux-2.6.12-rc2") Fixes: d886e87cb82b ("sound: make OSS sound core optional") Signed-off-by: Randy Dunlap Reported-by: kernel test robot Closes: lore.kernel.org/r/202307141416.vxuRVpFv-lkp@intel.com Cc: Richard Weinberger Cc: Anton Ivanov Cc: Johannes Berg Cc: linux-um@lists.infradead.org Cc: Tejun Heo Cc: Takashi Iwai Cc: Jaroslav Kysela Cc: Masahiro Yamada Cc: Nathan Chancellor Cc: Nick Desaulniers Cc: Nicolas Schier Cc: linux-kbuild@vger.kernel.org Cc: alsa-devel@alsa-project.org --- v2: don't delete the HOSTAUDIO Kconfig entry (Masahiro) v3: drop HOSTAUDIO and use CONFIG_UML_SOUND for it in Makefile (Takashi); add SOUND depends on "|| UML" to HAS_IOMEM v4: use depends on instead of select for SOUND (Masahiro); use Closes: instead of Link: arch/um/drivers/Kconfig | 16 +++------------- arch/um/drivers/Makefile | 2 +- sound/Kconfig | 2 +- 3 files changed, 5 insertions(+), 15 deletions(-) diff -- a/arch/um/drivers/Kconfig b/arch/um/drivers/Kconfig --- a/arch/um/drivers/Kconfig +++ b/arch/um/drivers/Kconfig @@ -111,24 +111,14 @@ config SSL_CHAN config UML_SOUND tristate "Sound support" + depends on SOUND + select SOUND_OSS_CORE help This option enables UML sound support.
