Thanks for doing that work, and sorry that it took me so long to
respond.

I cannot test it now (no IR receiver at hand), but I hope this
is fixed in CVS like so:

diff -u -p -r1.12 av7110_ir.c
--- drivers/media/dvb/ttpci/av7110_ir.c	3 May 2004 16:29:28 -0000	1.12

@@ -195,6 +195,7 @@ int __init av7110_ir_init(void)

 	remove_proc_entry("av7110_ir", NULL);
 	av7110_unregister_irc_handler(av7110_emit_key);
 	input_unregister_device(&input_dev);


It would be cool if you could report back if that fix works for you.

Regards,
Johannes
