Argh, the reasoning in that suggestion was:

	you need to include linux/mod_devicetable.h for kernel_ulong_t.

(https://lore.kernel.org/all/1c41ecc9-d951-45df-b933-1934e1381663@xxxxxxxxxx/).

This is wrong:

	$ git grep kernel_ulong_t v7.3-rc1:include/linux/mod_devicetable.h || echo void
	void

Please drop the inclusion of <linux/mod_devicetable.h> again, the only
effect of including is that you introduce a bunch of unneeded build
dependencies and I'm fighting to get rid of that file.

Also note that the driver is already using struct platform_device_id
which obviously has a member with type kernel_ulong_t. If you'd need an
additional header for kernel_ulong_t, the driver wouldn't have compiled
already before.

<linux/platform_device.h> already pulls in the definition of struct
platform_device_id and thus also kernel_ulong_t. Please rely on that or
if you want to go full iwyu include <linux/device-id/platformh.>

Best regards
Uwe
