The uio device should not fail on open just because one memory allocation fails. The device might export several regions, the failure of some of which may or may not be a problem for the user space driver. Failing regions will remain unmapped, and successful regions will be mapped and exported to user space. Also deals with the case where failing to map a region after successfully allocating others would not unmap the successfully allocated regions before dying.
