Driver core: add missing kset uevent
We get uevents for a bus/class going away, but not one registering.
Add the missing uevent in kset_register(), which will send an
event for a new bus/class. Suppress all unwanted uevents for bus
subdirectories like /bus/*/devices/, /bus/*/drivers/.
Now we get for module usbcore:
add /module/usbcore (module)
add /bus/usb (bus)
add /class/usb_host (class)
add /bus/usb/drivers/hub (drivers)
add /bus/usb/drivers/usb (drivers)
remove /bus/usb/drivers/usb (drivers)
remove /bus/usb/drivers/hub (drivers)
remove /class/usb_host (class)
remove /bus/usb (bus)
remove /module/usbcore (module)
instead of:
add /module/usbcore (module)
add /bus/usb/drivers/hub (drivers)
add /bus/usb/drivers/usb (drivers)
remove /bus/usb/drivers/usb (drivers)
remove /bus/usb/drivers/hub (drivers)
remove /class/usb_host (class)
remove /bus/usb/drivers (bus)
remove /bus/usb/devices (bus)
remove /bus/usb (bus)
remove /module/usbcore (module)
