sound: mpu401.c: make return of 0 explicit
Delete unnecessary local variable whose value is always 0 and that hides the fact that the result is always 0. A simplified version of the semantic patch that fixes this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @r exists@ local idexpression ret; expression e; position p; @@ -ret = 0; ... when != ret = e return - ret + 0 ; // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Signed-off-by: Takashi Iwai <tiwai@suse.de>
