sizeof(codec->reg_cache) is just the size of the pointer. Elsewhere in the file, codec->reg_cache is used with sizeof(wm8900_reg_defaults), so the code is changed to do the same here.
A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/)
// <smpl> @@ expression *x; expression f; type T; @@
*f(...,(T)x,...) // </smpl>
