Subject: drivers:misc: ti-st: fix unexpected UART close
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=651d62a8b0378b911f083a1712d9d228894f46d8;p=deliverable%2Flinux.git

drivers:misc: ti-st: fix unexpected UART close

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.
