ASoC: rsnd: enable SRC sync even FIN = FOUT (67923f77) · Commits · 戴 / test

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 Signed-off-by:
