Subject: [PATCH v4 10/11] cxl/pmem: Replace match_nvdimm_bridge() with API
 device_match_type()

From: Zijun Hu <quic_zijuhu@...cinc.com>

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().
