ASoC: SDCA: fix finding wrong entity
This patch fixes an issue like: where searching for the entity 'FU 11' could incorrectly match 'FU 113' first. The driver should first perform an exact match on the full string name. If no exact match is found, it can then fall back to a partial match. Fixes: 48fa77af2f4a ("ASoC: SDCA: Add terminal type into input/output widget name") Reviewed-by: Charles Keepax <ckeepax@opensource.cirrus.com> Signed-off-by: Shuming Fan <shumingf@realtek.com> Link: https://patch.msgid.link/20260325110406.3232420-1-shumingf@realtek.com Signed-off-by: Mark Brown <broonie@kernel.org>
