Fix check_patch.pl warning: WARNING: Prefer kmalloc_array over kmalloc with multiply +bps = kmalloc(align_space * sizeof((*data)->bps), GFP_KERNEL); WARNING: Prefer kmalloc_array over kmalloc with multiply +bps_bo = kmalloc(align_space * sizeof((*data)->bps_bo), GFP_KERNEL); kmalloc_array has multiply overflow check, which will be safer.
