From c5dc3b98fffaf183bb3d5bf690bfab9f6705c5e1 Mon Sep 17 00:00:00 2001 From: Antti Palosaari Date: Sun, 9 Dec 2012 13:45:42 -0300 Subject: [media] fc0012: remove unused callback and correct one comment There is no need to keep dummy sleep() callback implementation as DVB-core checks existence of it before calls callback. Due to that we can remove it. FC0012 is based of direct-conversion receiver architecture (aka Zero-IF) where is no IF used. Due to that IF is always 0 Hz. Fix comment to point that.
