Subject: [PATCH] serdev: Get serdev controller's name by dev_name()
Date: Wed, 23 Apr 2025 22:27:00 +0800 [thread overview]
Message-ID: <20250423-fix_serdev-v1-1-26ca3403fd33@quicinc.com> (raw)
From: Zijun Hu <quic_zijuhu@quicinc.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.
