I think this style change isn't really that good.
rdesc0 is:

struct rdesc0 {
	__le16 RSR;		/* Receive status */
	__le16 len;		/* bits 0--13; bit 15 - owner */
};

I think it more sensible to either set the fields
in the struct to 0 or to memset the struct to 0.

If checkpatch warns about this, it's wrong.

why not just remove all these commented-out lines?

perhaps just (u8 *)mask_pattern?

bad alignment?
