[PATCH -next] ASoC: codecs: lpass: Fix passing zero to 'PTR_ERR'

[YueHaibing]

sound/soc/codecs/lpass-macro-common.c:28 lpass_macro_pds_init() warn: passing zero to 'PTR_ERR'
sound/soc/codecs/lpass-macro-common.c:38 lpass_macro_pds_init() warn: passing zero to 'PTR_ERR'
sound/soc/codecs/lpass-macro-common.c:54 lpass_macro_pds_init() warn: passing zero to 'ERR_PTR'

dev_pm_domain_attach_by_name() may return NULL, set 'ret' as
-ENODATA to fix this warning.

Fixes: 1a8ee4cf8418 ("ASoC: codecs: Fix error handling in power domain init and exit handlers")
