Normally this issue should have been fixed by e9ac8e84f0 "hw/arm/sysbus-fdt: Only call match_fn callback if the type matches". Please can you confirm?

In match function it should not call OBJECK_CHECK. When there is a mismatch, we should continue to match rather than assert(). Signed-off-by: Peng Hao <peng.hao2@zte.com.cn> --- hw/arm/sysbus-fdt.c | 7 ++++++- 1 file changed, 6 insertions(+), 1 deletion(-)
