While being more verbose using a named initializer yields easier to
understand code and doesn't rely on the two hidden zeros in the
PCI_VDEVICE macro.

This doesn't introduce any changes to the compiled result of the array,
which was confirmed with an ARCH=x86 build.

Hello,

while being a cleanup that can stand on its own this is also a
preparation for making driver_data an anonymous union that requires that
.driver_data is initialized by name and not by list order. The union
allows to do

	-	{ PCI_VDEVICE(INTEL, PCI_DEVICE_ID_VLV_PMC), .driver_data = (kernel_ulong_t)&byt_data },
	+	{ PCI_VDEVICE(INTEL, PCI_DEVICE_ID_VLV_PMC), .driver_data_ptr = &byt_data },

and

	-	const struct pmc_data *data = (struct pmc_data *)ent->driver_data;
	+	const struct pmc_data *data = ent->driver_data_ptr;

then.

Best regards
Uwe

Thank you for your contribution, it has been applied to my local
review-ilpo-next branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-next branch only once I've pushed my
local branch there, which might take a while.

The list of commits applied:
[1/1] platform/x86: pmc_atom: Use named initializer for pci_device_id array
