drivers:misc: ti-st: avoid a misleading dbg msg
Pavan Savoy [Wed, 10 Aug 2011 15:18:30 +0000 (10:18 -0500)]
Previously the private data of each protocol registered to use ST was
used to determine whether the protocol was registered to use shared
transport or otherwise.
However, now a flag is_registered is maintained to identify whether a
protocol intends to use ST.
Upon closing of the UART the error message relevant to this lack of
un-registration was misleading and this patch fixes that.
