Browse source 
Merge a new ACPI IRQ override quirk for Eluktronics MECH-17 (Gannon
Kolding) and an acpi_data_prop_read() fix making it reflect the OF
counterpart behavior in error cases (Andy Shevchenko).

* acpi-property:
  ACPI: property: Fix return value for nval == 0 in acpi_data_prop_read()

* acpi-resource:
  ACPI: resource: IRQ override for Eluktronics MECH-17
