    Subject[PATCH 1/8] drivers:misc: ti-st: avoid a misleading dbg msg
    Date
    From: Pavan Savoy <pavan_savoy@ti.com>

    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.
