Subject: [PATCH 3.2 062/140] usb: add RESET_RESUME for ELSA MicroLink 56K

3.2.100-rc1 review patch.  If anyone has any objections, please let me know.

------------------

From: Oliver Neukum <oneukum@...e.com>

commit b9096d9f15c142574ebebe8fbb137012bb9d99c2 upstream.

This modem needs this quirk to operate. It produces timeouts when
resumed without reset.
