[dropped a few lists from Cc: that are off-topic for this mail] Hello,
while creating this patch series I looked at ps3_system_bus_shutdown(). I think the BUG_ON(!drv) in (now) line 422 can be easily triggered when there is a device without driver. (Try unbinding via sysfs before shutdown.) Also the BUG in (now) line 437 seems possible to trigger. Consider a driver that doesn't have the two callbacks, e.g. because there is nothing special to do on shutdown and probe only used devm_* resources. While at it, I find it surprising that the remove callback is called if there is no shutdown callback.
