Nitpick: Half of the commit message is redundant. From the reader/maintainer point of view, presented opinions and suggestions are fine as a part of cover-letter but not in the long run from git log level. > Signed-off-by: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> > Acked-by: Mark Brown <broonie@kernel.org> > Reviewed-by: Kai Vehmanen <kai.vehmanen@linux.intel.com> > Reviewed-by: Amadeusz Sławiński <amadeuszx.slawinski@linux.intel.com> Nitpick: commit title is not a sentence, should not end with full stop. > --- > sound/soc/intel/avs/core.c | 13 +++++++++---- > 1 file changed, 9 insertions(+), 4 deletions(-) > > diff --git a/sound/soc/intel/avs/core.c b/sound/soc/intel/avs/core.c > index bbb40339c75f..8a2063958248 100644 > --- a/sound/soc/intel/avs/core.c > +++ b/sound/soc/intel/avs/core.c > @@ -191,10 +191,6 @@ static void avs_hda_probe_work(struct work_struct *work) > > pm_runtime_set_active(bus->dev); /* clear runtime_error flag */ > > - ret = snd_hdac_i915_init(bus, true); > - if (ret < 0) > - dev_info(bus->dev, "i915 init unsuccessful: %d\n", ret); > - > snd_hdac_display_power(bus, HDA_CODEC_IDX_CONTROLLER, true); > avs_hdac_bus_init_chip(bus, true); > avs_hdac_bus_probe_codecs(bus); > @@ -465,10 +461,19 @@ static int avs_pci_probe(struct pci_dev *pci, const struct pci_device_id *id) > pci_set_drvdata(pci, bus); > device_disable_async_suspend(dev); > > + ret = snd_hdac_i915_init(bus, false); > + if (ret == -EPROBE_DEFER) > + goto err_i915_init; > + else if (ret < 0) The 'else' part seems redundant. s/else if/else/.
