Thanks, I will add this text to commit message. The resource_size_t is used in 
dwc3 structure
defined in drivers/usb/dwc3/core.h

struct dwc3 {
        ....
        struct resource  xhci_resource[DWC3_XHCI_RESOURCES_NUM];
        ..
};
The resource structure defined in include/linux/ioport.h 
struct resource {
        resource_size_t start;
        resource_size_t end;
}

>Also, please fix your mailer to break at 80 chars per line.

Sure.

Regards
Ravi
