From bc3e5c7fc20d3c09667067878fb7a55dd9fc041d Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Fri, 21 Dec 2007 11:18:32 -0300 Subject: [PATCH] V4L/DVB (6881): include struct analog_demod_ops directly inside struct dvb_frontend Rather than using a pointer, include struct analog_demod_ops directly inside struct dvb_frontend. This will allow us to use dvb_attach in the future, along with removing the need to check the ops structure before having to check the pointer to the method being called.
