Subject: kobj->state_initialized is never set to 0
Date: Fri, 20 Jul 2018 15:33:22 -0300	[thread overview]
Message-ID: <CAPW4XYai0qOy+6T8hP9A3QgG5PCfYHo6pp=U-HOk7-zFuUosiA@mail.gmail.com> (raw)

Hi,

I am simulating hotplugging a platform device (to the
media/platform/vimc driver), so I register it using
platform_device_register, then I unregister it with
platform_device_unregister, then I register it again, but the code
doesn't allow me to register something that was registered before due
to this line:

    https://github.com/torvalds/linux/blob/master/lib/kobject.c#L334

The variable kobj->state_initialized is set to 1 at

    https://github.com/torvalds/linux/blob/master/lib/kobject.c#L194

but it is never set to 0 again.

Is this how it is supposed to work? Or kobj->state_initialized is set
to 0 somewhere else I couldn't find?

Thanks
Helen
