commit abf03184a3 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.
