ALSA: sound/core/pcm_compat.c: adjust array index

Convert array index from the loop bound to the loop index. A simplified version of the semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression e1,e2,ar; @@ for(e1 = 0; e1 < e2; e1++) { <... ar[ - e2 + e1 ] ...> } // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Cc: <stable@kernel.org> Signed-off-by: Takashi Iwai <tiwai@suse.de>
