[PATCH v5 2/9] ASoC: soc-core: Allow searching dai driver name in snd_soc_find_dai

From: Jeffy Chen
Date: Tue Aug 22 2017 - 04:03:20 EST


Currently we are searching dai name in snd_soc_find_dai, which could
either be dai driver name or component device name(for legacy naming).

Allow searching dai driver name in snd_soc_find_dai too, so that we can
use dai driver name to find legacy naming dais.

Changes in v5:
Allow searching for dai driver name in snd_soc_find_dai, instead of
hacking non-zero device id to avoid legay dai naming.

Changes in v4: None
Changes in v3: None
Changes in v2: None
