Merge tag 'acpi-4.12-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI fix from Rafael Wysocki:
"This fixes the ACPI-based enumeration of some I2C and SPI devices
broken in 4.11.
Specifics:
- I2C and SPI devices are expected to be enumerated by the I2C and
SPI subsystems, respectively, but due to a change made during the
4.11 cycle, in some cases the ACPI core marks them as already
enumerated which causes the I2C and SPI subsystems to overlook
them, so fix that (Jarkko Nikula)"
