From 9185ef6787f1c8f1c06aa0cb3c7746fb4f101f50 Mon Sep 17 00:00:00 2001 From: "Denis V. Lunev" Date: Sat, 3 May 2008 06:34:05 +1000 Subject: [POWERPC] Assign PDE->data before gluing PDE into /proc tree Simply replace proc_create and further data assigned with proc_create_data. No need to check for data!=NULL after that. Signed-off-by: Denis V. Lunev Cc: Alexey Dobriyan Cc: Eric W.
