Subject: [PATCH v2 08/32] net: dsa: Adapt for constified
 device_find_child()

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

device_find_child() has been constified to take new match function type:
typedef int (*device_match_t)(struct device *dev, const void *data);

Make dev_is_class() take a const pointer to adapt for the new type.
