| Subject: [PATCH 075/299] ASoC: rsnd: enable SRC sync even FIN = FOUT |
| |
| Current SRC (= Sampling Rate Converter) is supporting |
| SYNC mode and ASYNC mode. Current src.c cares SRC if FIN != FOUT. |
| Here, SYNC mode will be used for tweak, so it will be used |
| even FIN = FOUT. This patch enables SRC sync in such situation |
