[PATCH] ACPI: Drop ACPI_NO_HARDWARE_INIT

From: Rafael J. Wysocki
Date: Sat Mar 26 2011 - 07:30:45 EST


From: Rafael J. Wysocki <rjw@xxxxxxx>

ACPI_NO_HARDWARE_INIT is only used by acpi_early_init() and
acpi_bus_init() when calling acpi_enable_subsystem(), but
acpi_enable_subsystem() doesn't check that flag, so it can be
dropped.
