The function initio_probe_one() allocates a DMA buffer without the GFP_KERNEL modifier, fix this by using (GFP_KERNEL | GFP_DMA) instead of only GFP_DMA as the probe happens in non-interrupt context. At the same time, change the if statement to the more typical kernel style. Eliminate the follow smatch warning: drivers/scsi/initio.c:2850 initio_probe_one() error: no modifiers for allocation.
