Subject: [PATCH 6/6] icE1usb: Add support for reporting remote alarm (RAI) as
 YELLOW alarm

In osmo-e1-hardware.git Change-Id Ic4f57cf79bd32cf75f81ef3073cb8d4a2d1857d8
the icE1usb firmware gained support for reporting the E1_ERR_F_RAI flag
via USB interrupt transfers.  Make use of that to report YELLOW alarm
via the usual DAHDI alarms infrastructure.
