Suggested-by: Matthias Reichl <hias@...us.com> Signed-off-by: Christian Hewitt <christianshewitt@...il.com> --- The meson AIU/AXG drivers currently require alsa confs based on the board model name which is unique to each board. This is very flexible for audio use-cases, but not very maintainable for distros with a single use-case that need to support a large number of different Amlogic boards. Using a driver name to match the card conf instead of card/model name reduces the number of confs needed in the LibreELEC (Kodi) distro from 41 to 2. sound/soc/meson/meson-card-utils.c | 1 + 1 file changed, 1 insertion(+) diff --git a/sound/soc/meson/meson-card-utils.c b/sound/soc/meson/meson-card-utils.c index 415cc0046e4b..29b0174f4b5c 100644 --- a/sound/soc/meson/meson-card-utils.c +++ b/sound/soc/meson/meson-card-utils.c @@ -302,6 +302,7 @@ int meson_card_probe(struct platform_device *pdev) priv->card.owner = THIS_MODULE; priv->card.dev = dev; + priv->card.driver_name = dev->driver->name; priv->match_data = data; ret = snd_soc_of_parse_card_name(&priv->card, "model"); -- 2.17.1
