      drivers:misc:ti-st: handle delayed tty receive · 764b0c4b
      Pavan Savoy authored
      When certain technologies shutdown their interface without waiting for
      the acknowledgement from the chip. The receive_buf from the TTY would be
      invoked a while after the relevant technology is unregistered.
      
      This patch introduces a new flag "is_registered" which maintains the
      state of protocols BT, FM or GPS and thereby removes the need to clear
      the protocol data from ST when protocols gets unregistered.
      
      This fixes corner cases when HCI RESET is sent down from bluetooth stack
      and the receive_buf is called from tty after 250ms before which
      bluetooth would have unregistered from the system.
      OR - when FM application decides to close down the device without
      sending a power-off FM command resulting in some RDS data or interrupt
      data coming in after the driver is unregistered.
