[SCSI] gdth: Add missing call to gdth_ioctl_free
Add missing call to gdth_ioctl_free before aborting. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression buf,ha,len,addr,E; @@ buf = gdth_ioctl_alloc(ha, len, FALSE, &addr) ... when != false buf != NULL when != true buf == NULL when != \(E = buf\|buf = E\) when != gdth_ioctl_free(ha, len, buf, addr) *return ...; // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
