Merge tag 'acpi-4.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull ACPI fixes ffrom Rafael Wysocki:
"Two stable-candidate fixes for the ACPI early device probing code
added during the 4.4 cycle, one fixing a typo in a stub macro used
when CONFIG_ACPI is unset and one that prevents sleeping functions
from being called under a spinlock (Lorenzo Pieralisi)"
* tag 'acpi-4.8-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
ACPI / drivers: replace acpi_probe_lock spinlock with mutex
ACPI / drivers: fix typo in ACPI_DECLARE_PROBE_ENTRY macro
