From e4b81c966e03ee280492e75cdd569f8495cb2a06 Mon Sep 17 00:00:00 2001 From: Holger Freyther Date: Tue, 8 Jul 2008 18:38:16 +0100 Subject: [PATCH] From cede5c6c9b06ecbb0f7f2df7b7070092b87ddaf8 Mon Sep 17 00:00:00 2001 Subject: [PATCH] [pcf50633] Avoid ooops on start with inserted usb cable The pcf50633_global might not be initialized when we get the first usb interrupt. We would oops inside the dev_err because we made up a struct device.
