From 65e8d29f7a37faaf9c73c633447bebd4b31b2c89 Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Tue, 22 Apr 2008 14:41:50 -0300 Subject: V4L/DVB (7126): tuner: move tuner type ID check to simple_tuner_attach Move tuner type ID check from tuner-core::set_type to simple_tuner_attach. Since tuner-core forwards all attach requests to tuner-simple as the default case, unless a specific attach function is specified in set_type, this change is an appropriate cleanup.
