From a5e36d20897ff8317e722fceb4d9eea3e4a5906b Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Mon, 28 Nov 2005 22:15:46 +0000 Subject: [PATCH] [PATCH] USB: Correct ohci-pxa27x suspend/resume struct confusion The device data in ohci-pxa27x is a struct hcd, not a struct ohci_hcd. This correct the suspend/resume calls to account for this and adds some code to invalidate the platform data when the module is removed.
