Subject: [PATCH 5.10.y 2/2] usb: musb: omap2430: fix device leak at unbind
Date: Thu, 21 Aug 2025 12:14:13 -0400 [thread overview]
Message-ID: <20250821161413.775044-2-sashal@kernel.org> (raw)
In-Reply-To: <20250821161413.775044-1-sashal@kernel.org>
From: Johan Hovold <johan@kernel.org>
[ Upstream commit 1473e9e7679bd4f5a62d1abccae894fb86de280f ]
Make sure to drop the reference to the control device taken by
of_find_device_by_node() during probe when the driver is unbound.
Fixes: 8934d3e4d0e7 ("usb: musb: omap2430: Don't use omap_get_control_dev()")
