Today's -tip failed to build because commit 0d204c34e85d1d63e5fdd3e3192747daf0ee7ec1 ("thinkpad-acpi: basic ALSA mixer support (v2)") from today's upstream kernel causes the following build failure on x86, for CONFIG_THINKPAD_ACPI=y && CONFIG_SOUND=m:
drivers/built-in.o: In function `volume_alsa_notify_change': thinkpad_acpi.c:(.text+0x2d5c2d): undefined reference to `snd_ctl_notify' thinkpad_acpi.c:(.text+0x2d5c47): undefined reference to `snd_ctl_notify'
I've applied the patch below to tip:out-of-tree.
Thanks,
Ingo
-----------------> acpi: Build CONFIG_SOUND=m build failure in CONFIG_THINKPAD_ACPI=y
Today's -tip failed to build because thinkpad_acpi.c uses sound facilities unconditionally, without expressing its dependency on the sound subsystem:
drivers/built-in.o: In function `volume_alsa_notify_change': thinkpad_acpi.c:(.text+0x2d5c2d): undefined reference to `snd_ctl_notify' thinkpad_acpi.c:(.text+0x2d5c47): undefined reference to `snd_ctl_notify'
Add a Kconfig dependency on SOUND to remedy this.
