Subject: staging: comedi: das16: board is not a PCI device
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ed07758759ad3fd2b7b18a1f821c2ad7e84376d0;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

staging: comedi: das16: board is not a PCI device

The DAS16 board is an ISA device not a PCI device. For aesthetics, use
dma_{alloc,free}_coherent() to allocate and free the DMA buffers instead
of the PCI versions.
