From c2f128a1fed866dca94d52b3f0b1e40726e2352a Mon Sep 17 00:00:00 2001 From: Jiri Slaby Date: Mon, 5 Mar 2012 14:52:03 +0100 Subject: [PATCH] NET: pc300, do not zero global variables They are in .bss which is initialized to zeros when the module is loaded/kernel booted. What a strange way to do the initialization once in the pci probe routine...
