I wonder why buildbot did not spot it for the branch I > submitted to rc3. Things happen, I guess... Maybe because there was no user that can hit with randconfig. It was a preliminary fix for the change I recently put after the rc3 release, and now it surfaced. thanks, Takashi

CONFIG_ACPI is boolean but let's also change it to use IS_REACHABLE() to future-proof it against becoming tristate. Somehow despite testing various combinations of CONFIG_I2C and CONFIG_ACPI we missed the combination CONFIG_I2C=m, CONFIG_ACPI=y.
