From 8fd79579c9ccc6ac98d02c2c97d5fb367cfc0e29 Mon Sep 17 00:00:00 2001 From: Ondrej Zary Date: Tue, 14 May 2013 16:54:43 -0300 Subject: [media] tea575x-tuner: move HW init to a separate function Move HW initialization to separate function to allow using the code without the v4l parts. This is needed for use in the bttv driver.
