[PATCH v3] um/drivers: fix hostaudio build errors
Posted by Randy Dunlap 2 years, 1 month ago 
Use "select"s to ensure that the required kconfig symbols are set
as expected.
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

This would be the only instance that select's SOUND.
Perhaps, this could be 'depends on SOUND'.
(in that case, arch/um/configs/*_defconfig needs modification).

Just my two cents.

Oh, good point, and one that I agree with.

I'll send a v4.

Takashi, I don't know who will merge the patch, but I would expect
that one of the UML maintainers to merge it.... FWIW.

Thanks.

I'm not sure who should take it.  If it's preferred through sound.git
tree, let me know.
