You would just need to add an 'attach' method to the dvb_frontend structure and pass that pointer to symbol_put_addr(). I think you could get away with passing a pointer to any function in the frontend module, it doesn't have to be the same one you got with symbol_get() since the reference count is for the whole module, not individual symbol. But.... There are no users of symbol_put_addr(), and there is a reason! Ever since this patch: Fix race between CONFIG_DEBUG_SLABALLOC and modules Sun, 27 Jun 2004 17:55:19 +0000 (17:55 +0000) http://www.kernel.org/git/?p=linux/kernel/git/torvalds/old-2.6-bkcvs.git;a=commit;h=92b3db26d31cf21b70e3c1eadc56c179506d8fbe using symbol_put_addr() will hang your kernel. So, probably best not to use it. _______________________________________________ linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
