* driver: replace dev_request_mem_region with dev_request_mem_resourceSascha Hauer2016-03-071-3/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | dev_request_mem_region doesn't work properly one some SoCs on which PTR_ERR() values clash with valid return values from dev_request_mem_region. Replace them with dev_request_mem_resource where possible.
