+Subject: [PATCH] port-probe: add more retries for port AT probing
+
+Launching the MM on target's boot fails to detect the XBee cellular
+because this needs more time to complete the initialization. So add some
+more retries for the AT port probing to allow the XBee cellular to be
+detected.
+
+Upstream-Status: Inappropriate [embedded specific (Xbee cellular)]
