From 458d337d90095b5d546c442e37de79db65fc9dfd Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Wed, 10 Sep 2008 00:39:20 -0400 Subject: add a general-purpose callback pointer to struct dvb_frontend From: Michael Krufky Remove tuner_callback pointers from tuner driver configuration and private state structures, replaced with a general-purpose callback pointer within struct dvb_frontend. A new parameter is added to the callback function, called component. This allows us to use this callback pointer by frontend components other than the tuner, if need be. So far, this is only used by tuner drivers.
