The DMA API removed support for not passing in a device a long time ago, so remove the NULL checks.What happens with ISA devices?
For actual drivers they've been switched to struct isa_driver, which provides a struct device. For some of the special case like the arch/arm/kernel/dma-isa.c we now use static struct device instances. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
