Hi!


I've found out in RTAI's 16550a driver, that uses RTDM, the following 
comment:

     /*We should disable the line now, but this requires counting
      * enable/disable, something not yet implemented by the core.
      * At the moment this call could starve other users sharing the
      * same line.
     rtdm_irq_disable(&ctx->irq_handle);*/
     rtdm_irq_free(&ctx->irq_handle);

Is this still true? I mean, if i free the device at device close, should 
i expect that i need to request the irq again?

I'm trying to ckeck what to expect about these calls.


Thanks for the help
