Hey Greg,
Marc was able to get me a backtrace for that bootup hang scenario that Pierre noted here [1]. A Tested-by is still pending, but I am certain this is the issue, and it may impact more than just the one platform if that "empty_attrs" pattern has been repeated anywhere else in the kernel.
I also took some time to document how to use the helpers a bit better, and introduce DEFINE_SIMPLE_SYSFS_GROUP_VISIBLE() for cases where all that matters is group visibility and not per attribute visibility.
I'll just queue these up now on my normal driver-core-next branch, and not worry about a stable tag as I doubt anyone wants that now. But if they do, please let me know and I can provide one.
thanks for the quick fixes!
