From 185e4768b864b3b65c5d2cdca9be556d493f15e1 Mon Sep 17 00:00:00 2001 From: Michael Krufky Date: Sat, 29 Sep 2012 16:05:26 -0300 Subject: [PATCH] [media] tda18271: enter low-power standby mode at the end of tda18271_attach() Ensure that unnecessary features are powered down at the end of the attach() function. If the configuration requires the loop thru or xtout features, they will remain enabled. Thanks to Antti Palosaari for noticing the additional power consumption.
