Subject: [PATCH] serdev: Get serdev controller's name by dev_name()

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

serdev_controller_add() uses hardcoded serdev controller's name, and that
may be wrong once user changes the name after serdev_controller_alloc().

Fix by using dev_name() instead of hardcoded name.
