[Qemu-devel] [PATCH] qdev: Remove some non-run codes in qdev_walk_children().

[Zhi Yong Wu]

As you have known, qdev_reset_one() forever return a ZERO value to its caller, 
so some branches can not be forever covered in qdev_walk_children().

I thought that the return value for dev->info->reset(dev) can be returned, but 
dev->info->reset(dev) is referring to a function with void type.
