From c74c120a21d87b0b6925ada5830d8cac21e852d9 Mon Sep 17 00:00:00 2001 From: Alexey Dobriyan Date: Tue, 29 Apr 2008 01:01:44 -0700 Subject: [PATCH] proc: remove proc_root from drivers Remove proc_root export. Creation and removal works well if parent PDE is supplied as NULL -- it worked always that way. So, one useless export removed and consistency added, some drivers created PDEs with &proc_root as parent but removed them as NULL and so on.
