acpi-dma: convert to return error code when asked for channel Currently acpi_dma_request_slave_chan_by_index() and acpi_dma_request_slave_chan_by_name() return only requested channel or NULL. This patch converts them to return appropriate error code instead of NULL in case of unsuccessfull request.
