Subject: v4l2-compliance: Fix use of routing on 32-bit platforms Author: Tomi Valkeinen <tomi.valkei...@ideasonboard.com> Date: Wed Apr 3 13:15:44 2024 +0300 At the moment we do: routing.routes = (__u64)&routes; On 32-bit platforms the 32-bit address will be sign-extended, possibly resulting setting the address to, e.g., 0xff000000 -> 0xffffffffff000000. Fix this by converting the address to uintptr_t.
