From 7e61559f6199bb387037abfc7d10a893973561fc Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Tue, 6 Nov 2007 11:43:42 -0500 Subject: USB: keep track of whether interface sysfs files exist This patch (as1009) solves the problem of multiple registrations for USB sysfs files in a more satisfying way than the existing code. It simply adds a flag to keep track of whether or not the files have been created; that way the files can be created or removed as needed.
