Subject: [PATCH] usb: musb: mpfs: fix phy unregister in remove()
Date: Mon, 14 Sep 2026 19:09:13 +0800	[thread overview]
Message-ID: <20260914-mpfs-v1-1-0bb5b6c2e67c@gmail.com> (raw)

mpfs_remove() passed the glue platform device instead of the
registered generic PHY to usb_phy_generic_unregister(). This
unregistered the glue device from within its own remove
callback and leaked glue->phy.

Pass glue->phy instead.

Fixes: 7a96b6ea90a4 ("usb: musb: Add support for PolarFire SoC's musb controller")
