Since the changes in

	commit f748a07a0b64 ("PCI: Remove legacy pcim_release()")

all pcim_enable_device() does is set up a callback that disables the
device from being disabled from driver detach. The function
pcim_pin_device() prevents said disabling. pcim_enable_device(),
therefore, sets up an action that is removed immediately afterwards by
pcim_pin_device().

Replace pcim_enable_device() with pci_enable_device() and remove the
unnecessary call to pcim_pin_device().
