From e7b419b69212f3c3489ae808f26d2a0d2b52fe9c Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Mon, 26 Mar 2007 16:39:20 -0300 Subject: [PATCH] V4L/DVB (5610): M920x: remove duplicated code Some of the devices supported by the m920x driver have identical functions used for tuner_attach and frontend_attach. This patch consolidates the functions in question, and updates the debug code to be generic for each. This patch decreases the size of the kernel.
