make hybrid_tuner_request_state tolerant of devices without i2c adapters
From: Michael Krufky <mkrufky@linuxtv.org> 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. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org>
