From f9c99bb8b3a1ec81af68d484a551307326c2e933 Mon Sep 17 00:00:00 2001 From: Alan Stern Date: Tue, 2 Jun 2009 11:53:55 -0400 Subject: USB: usb-serial: replace shutdown with disconnect, release This patch (as1254) splits up the shutdown method of usb_serial_driver into a disconnect and a release method. The problem is that the usb-serial core was calling shutdown during disconnect handling, but drivers didn't expect it to be called until after all the open file references had been closed. The result was an oops when the close method tried to use memory that had been deallocated by shutdown.
