From 3551bb176929327211be22bd960a486ea8499d87 Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Sun, 10 Feb 2008 19:02:59 -0500 Subject: make hybrid_tuner_request_state tolerant of devices without i2c adapters From: Michael Krufky Some dvb demodulators access the tuner directly without using i2c. In these cases, i2c_adap may be NULL. This patch fixes hybrid_tuner_request_state to allow for NULL i2c_adapters.
