commit 37768adf9a1d49aeac0db1ba3dc28b3274b7b789 upstream

This patch fixes a problem with any mos7840 device where the use of the
field "minor" before it is initialised results in all the devices being
overlaid in memory (minor = 0 for all instances)

USB: usb-serial: replace shutdown with disconnect, release 2009-12-08T19:17:31+00:00 Alan Stern stern@rowland.harvard.edu 2009-12-01T15:01:08+00:00 f10f9dd87161b70da6ec3d257c1f01a6ac02536f This is commit f9c99bb8b3a1ec81af68d484a551307326c2e933 back-ported to 2.6.27.39. This patch (as1254-2) 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.

2.6.27.39.

This patch (as1254-2) 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.

usb-serial: fix crash when sub-driver updates firmware 2009-10-22T04:51:09+00:00 Alan Stern stern@rowland.harvard.edu 2009-05-27T15:25:52+00:00 66f7234efcc7182ee7f3e5884ae385b2ff4dce87 commit 0a3c8549ea7e94d74a41096d42bc6cdf43d183bf upstream. This patch (as1244) fixes a crash in usb-serial that occurs when a sub-driver returns a positive value from its attach method, indicating that new firmware was loaded and the device will disconnect and reconnect. The usb-serial core then skips the step of registering the port devices; when the disconnect occurs, the attempt to unregister the ports fails dramatically. This problem shows up with Keyspan devices and it might affect others as well. When the attach method returns a positive value, the patch sets num_ports to 0. This tells usb_serial_disconnect() not to try unregistering any of the ports; instead they are cleaned up by destroy_serial().
