Currently DAPM has a lot of similar code to handle errors from
snd_soc_dapm_new_control_unlocked, and much of this code does
not really accurately reflect what the function returns.
Firstly, most places will check for a return value of
-EPROBE_DEFER and silence any error messages in that case. The
one notable exception here being dapm_kcontrol_data_alloc
which does currently print any error messages in the case
of snd_soc_dapm_new_control_unlocked returning NULL or an
error. Additionally the error prints being silenced in these
case are redundant as snd_soc_dapm_new_control_unlocked can
only return -EPROBE_DEFER or NULL when failing.
Secondly, most places will treat a return value of NULL as
an -ENOMEM. This is not correct either since any error except
EPROBE_DEFER will cause a return value of NULL from
snd_soc_dapm_new_control_unlocked.
Centralise this handling and the error messages within
snd_soc_dapm_new_control_unlocked and update the callers
to simply check IS_ERR and return. Note that this update is
slightly simpler in the case of dapm_kcontrol_data_alloc where
that is fairly close to the handling that was already in place.

* Applied "ASoC: dapm: Move connection of CODEC to CODEC DAIs" to the asoc tree 2018-09-05 14:21 ` [PATCH v2 3/5] ASoC: dapm: Move connection of CODEC to CODEC DAIs Charles Keepax @ 2018-09-06 10:48 ` Mark Brown 0 siblings, 0 replies; 6+ messages in thread From: Mark Brown @ 2018-09-06 10:48 UTC (permalink / raw) To: Charles Keepax; +Cc: patches, alsa-devel, broonie, lgirdwood The patch ASoC: dapm: Move connection of CODEC to CODEC DAIs has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From 778ff5bb8689eb4fd05a72a409e32a3a34e23faf Mon Sep 17 00:00:00 2001 From: Charles Keepax <ckeepax@opensource.cirrus.com> Date: Wed, 5 Sep 2018 15:21:00 +0100 Subject: [PATCH] ASoC: dapm: Move connection of CODEC to CODEC DAIs Currently, snd_soc_dapm_connect_dai_link_widgets connects up the routes representing normal DAIs, however CODEC to CODEC links are hooked up through separate infrastructure in soc_link_dai_widgets. Improve the consistency of the code by using snd_soc_dapm_connect_dai_link for both types of DAIs.
