Also, is the interrupt mandatory ? All it does is to display a message. Looks very optional to me.It is a place holder for something more application specific. I could remove it, but I figured it would just get re-added when somebody takes the driver and modifies it for their needs. If this is a problem however, it can go. Please advise ..
Then this someone should add the code. For the time being, it just increases kernel size and may cause the driver to fail for no good reason. Plus, given the driver apparently works without interrupt, even then it should be optional, and the driver does not have to fail loading if it is not supported on a given platform. Thanks, Guenter
