Akinobu Mita a2cd4dcbb7 resource: fix false warning in __request_region() ... commit 91a229bb7b upstream. A warning is raised when __request_region() detects a conflict with a resource whose resource.desc is IORES_DESC_DEVICE_PRIVATE_MEMORY. But this warning is only valid for iomem_resources. The hmem device resource uses resource.desc as the numa node id, which can cause spurious warnings. This warning appeared on a machine with multiple cxl memory expanders. One of the NUMA node id is 6, which is the same as the value of IORES_DESC_DEVICE_PRIVATE_MEMORY. In this environment it was just a spurious warning, but when I saw the warning I suspected a real problem so it's better to fix it. This change fixes this by restricting the warning to only iomem_resource. This also adds a missing new line to the warning message.
