ACPI: PCI: Fix device reference counting in acpi_get_pci_dev()
Commit 63f534b8bad9 ("ACPI: PCI: Rework acpi_get_pci_dev()") failed to reference count the device returned by acpi_get_pci_dev() as expected by its callers which in some cases may cause device objects to be dropped prematurely. Add the missing get_device() to acpi_get_pci_dev(). Fixes: 63f534b8bad9 ("ACPI: PCI: Rework acpi_get_pci_dev()") Reported-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
