[Nouveau] [PATCH 08/10] drm: debugfs: remove debug directores using recursion.

[Maxim Levitsky]

Well, I implemented a custom debugfs file for nouveau,
but found it hard to remove it cleanly due to constrains on drm debugfs api.
I implemented a hack and then surprised that other drivers (intel and radeon) have exactly same ugly hack.
So why? Just one liner does the job.
This patch shouldn't break other driver, and with it, some code (the hacks) can be removed from them now.
