ALSA: sound/isa/gus: Correct code taking the size of a pointer
sizeof(share_id) is just the size of the pointer. On the other hand,
block->share_id is an array, so its size seems more appropriate.
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>
