From fd687502dc8037aa5a4b84c570ada971106574ee Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 16 Mar 2012 07:44:18 -0300 Subject: edac: Rename the parent dev to pdev MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit As EDAC doesn't use struct device itself, it created a parent dev pointer called as "pdev". Now that we'll be converting it to use struct device, instead of struct devsys, this needs to be fixed. No functional changes.

EDAC never obeyed this rule: it has a single malloc function that allocates all needed data into a single kzalloc. As this is not accepted anymore, change the allocation schema of the EDAC *_info structs to enforce this Kernel standard.
