Here checkpatch thinks that hydsn_card is an identifier rather
than a typedef.

It's defined as:
	typedef struct HYSDN_CARD {
	...
	} hysdn_card;

And that confuses checkpatch.

kernel source code style would not use a typedef for a struct.

A change would be to remove the typedef and declare this as:
	struct hysdn_card {
		...
	};

And then do a global:
	sed 's/\bhysdn_card\b/struct hysdn_card/g'

But that's not necessary as the driver is likely to be removed.
