Subject: [PATCH] misc: lan966x_pci: depopulate children on populate failure
Date: Tue, 16 Jun 2026 08:43:04 +0800 [thread overview]
Message-ID: <20260616004304.95117-1-pengpeng@iscas.ac.cn> (raw)
lan966x_pci_probe() loads the device-tree overlay and then populates
child devices from it. If of_platform_default_populate() fails after
creating any children, the error path removes the overlay without first
depopulating the partially-created children.
Mirror the remove path ordering on the populate failure path by
depopulating child devices before unloading the overlay.
