From 65087cfee50595185f6bbf3d78272eeb34186d2b Mon Sep 17 00:00:00 2001 From: Ariel Elior Date: Mon, 23 Jan 2012 07:31:55 +0000 Subject: bnx2x: handle CHIP_REVISION during init_one The macro `CHIP_IS_E1x' requires `bp' to be initialized. As `bp' is not yet initialized during this phase of `bnx2x_init_dev', it accessed uninitialized fields in the struct.
