Subject: [PATCH 13/13] drivers:misc: ti-st: fix unexpected UART close

From: Pavan Savoy <pavan_savoy@...com>

If suppose the UIM were to die and hence UART were to close when the
Bluetooth/FM or GPS is turned on, prep the ST for a state where-in if
the UIM comes back up, Bluetooth/FM/GPS can be turned on.
