From: Zijun Hu <redacted> Static match_nvdimm_bridge(), as matching function of device_find_child() matches a device with device type @cxl_nvdimm_bridge_type, and its task can be simplified by the recently introduced API device_match_type(). Replace match_nvdimm_bridge() usage with device_match_type().
