regmap_init() adds the initialised map to the device resources, which can be then obtained in the driver->probe function in a generic way with dev_reg_regmap(), which makes it independent from underlying hardware interface. This is useful when platform_devices are not simply memory mapped but must use custom way of accessing the registers.
Unfortunately the device core WARNs in a situation when probed devices has a non-empty resources list. This patch simply removes this check and doesn't seem to have any side effects.
