           Summary: acpi sysfs creates useless module aliases
           Product: ACPI
           Version: 2.5
          Platform: All
        OS/Version: Linux
              Tree: Mainline
            Status: NEW
          Severity: normal
          Priority: P1
         Component: Other
        AssignedTo: [email protected]
        ReportedBy: [email protected]
        Regression: No


This shows the list of exported module aliases from ACPI:
  grep . /sys/bus/acpi/devices/*/modalias

More than half of it are just 'acpi:device:' which looks rather useless to
export, and these values without meaning should better be suppressed.

These aliases cause ~70 needless calls to:
  /sbin/modprobe $MODALIAS
on every bootup.

We could filter that in userland, but prefer the fix at the ACPI sysfs to not
to export information without information. :)
