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.
