Ok, thanks.
I assume noone wants to invest some time into this old driver and covert
it to todays kernel IR infrastructure as suggested by Antti ? :-)
Then I'm going to send a patch with the
#if defined(CONFIG_MODULE) || defined(CONFIG_DVB_USB_AF9005_REMOTE)
approach.
That's at least better than leaving the bug unfixed.

Frank
