From 828d651c585c1c2a2b8d4e67da36c9f91124855a Mon Sep 17 00:00:00 2001 From: Hao Wu Date: Fri, 8 Jan 2021 11:09:45 -0800 Subject: [PATCH] hw/*: Use type casting for SysBusDevice in NPCM7XX A device shouldn't access its parent object which is QOM internal. Instead it should use type cast for this purporse. This patch fixes this issue for all NPCM7XX Devices.
