Hi,

I noticed that gpiolib does not explicitly remove the sysfs attributes it
created when exporting a gpio pin when the pin is unexported, ie when the
associated device is removed.

Are those attributes auto-removed when device_unregister() is called ?

Sorry if this is a dumb question - I have not noticed this anywhere else,
and I don't seem to be able to find the code actually performing auto-removal
of manually created attributes, so I wonder if this is a bug or intentional.

Thanks,
Guenter
