2.6.36-stable review patch. If anyone has any objections, please let us know.
------------------ From: Alan Stern <[email protected]> commit abf03184a31a3286fc0ab30f838ddee8ba9f9b7b upstream. This patch (as1437) fixes a bug in the usb-serial autosuspend handling. Since the usb-serial core now has autosuspend support, it must set the .supports_autosuspend member in every serial driver it registers. Otherwise the usb_autopm_get_interface() call won't work. This fixes Bugzilla #23012.
