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> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Takashi Iwai <tiwai@suse.de>
