Follow the rule taken in commit 35bd8c07db2c
("devres: keep both device name and resource name in pretty name")
and keep both device and resource names while requesting memory
regions for PCI config space to prettify e.g. /proc/iomem output:Before (DWC Host Controller): 18b00000-18b01fff : dbi 18b10000-18b11fff : config 18b20000-18b21fff : dbi 18b30000-18b31fff : config After: 18b00000-18b01fff : 18b00000.pci dbi 18b10000-18b11fff : 18b00000.pci config 18b20000-18b21fff : 18b20000.pci dbi 18b30000-18b31fff : 18b20000.pci config Since v1 [0]: - massage subject and commit message (Bjorn); - no functional changes.
