ACPI: allow drivers to request both device and system notify events
System notify events (0x00-0x7f) are common across all device types
and should be handled in Linux/ACPI, not in drivers. However, some
BIOSes use system notify events in device-specific ways that require
the driver to be involved.
This patch adds a ACPI_DRIVER_ALL_NOTIFY_EVENTS driver flag. When a
driver sets this flag and supplies a .notify method, Linux/ACPI calls
the .notify method for ALL notify events on the device, not just the
device-specific (0x80-0xff) events.
