From c76286bafc682740a3c83aebeacb2d304bd39184 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Sun, 26 Jan 2014 15:30:53 -0300 Subject: [PATCH] [media] drx-j: avoid calling power_down_foo twice When switching from one video standard to another one, power_down_vsb is called twice. Well, as the device is already in power_down mode, the second call always fail. This causes that any subsequent frontend set to fail as well: [145074.501243] drx39xyj:power_down_vsb: called [145089.195396] drx39xyj:power_down_vsb: error -5 [145089.195404] drx39xyj:ctrl_set_standard: error -5 [145089.195417] drx39xyj:drx39xxj_set_frontend: Failed to set standard! result=fffffffb [145089.195470] drx39xyj:ctrl_sig_quality: error -5 [145089.195473] drx39xyj:drx39xxj_read_ber: drx39xxj: could not get ber!
