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...
