Jan Viktorin 3ab4b2989e uio: fix dmem_region_start computation ... commit 4d31a2588a upstream. The variable i contains a total number of resources (including IORESOURCE_IRQ). However, we want the dmem_region_start to point after the last resource of type IORESOURCE_MEM. The original behaviour leads (very likely) to skipping several UIO mapping regions and makes them useless. Fix this by computing dmem_region_start from the uiomem which points to the last used UIO mapping.
