Revision 6778be4e520959659b27a441c06a84c9cb009085 authored by Robin Murphy on 07 November 2018, 16:30:32 UTC, committed by Rob Herring on 08 November 2018, 18:44:34 UTC
of_dma_configure() was *supposed* to be following the same logic as
acpi_dma_configure() and only setting bus_dma_mask if some range was
specified by the firmware. However, it seems that subtlety got lost in
the process of fitting it into the differently-shaped control flow, and
as a result the force_dma==true case ends up always setting the bus mask
to the 32-bit default, which is not what anyone wants.
Make sure we only touch it if the DT actually said so.
Fixes: 6c2fb2ea7636 ("of/device: Set bus DMA mask as appropriate")
