From acd7d952514485dbc41fa04b0d16be4002e31019 Mon Sep 17 00:00:00 2001 From: Nico Huber Date: Wed, 25 Jul 2012 10:33:05 +0200 Subject: Add initialization hook for chips MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Add an init() function to the chip_operations which will be called before bus enumeration. This allows to disable unused devices before they get enumerated.
