[PATCH 2/3] staging: greybus: arche-platform: fix memleak on probe failure

From: Johan Hovold

Date: Fri Dec 19 2025 - 06:00:05 EST


Make sure to depopulate the child devices in case of late probe
failures to avoid leaking the corresponding resources.

Fixes: fd60ac585607 ("greybus: arche-platform: Fix boot, poweroff and fw_flashing seq with APBs")
