It might be clearer to use a structure for this 16 byte thing.

There's a comment bit in the code:

/* cmdreq message: 
	u32 type
	u16 cmd
	u16 parm0
	u16 parm1
	u16 parm2
	u8  pad[4]

	total: 4 + 2 + 2 + 2 + 2 + 4 = 16
*/

It seems thought that this first u32 is actually
a series of u8s.

Maybe:

struct zd1201_cmdreq {
	u8	type;
	u8	seq;
	u8	a;
	u8	b;
	__le16	cmd;
	__le16	parm0;
	__le16	parm1;
	__le16	parm2;
	u8	pad[4];
};

And does this really need to be alloc'd?

maybe

struct zd1202_cmdreq request = {};

etc...
