From: Charles Keepax Date: Tue, 8 Aug 2023 13:20:12 +0000 (+0100) Subject: ASoC: intel: sof_sdw: Allow different devices on the same link X-Git-Tag: v6.6.17~3959^2^2~129 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=317dcdecaf7a42febb78c564df15fd817bf720b2;p=platform%2Fkernel%2Flinux-rpi.git ASoC: intel: sof_sdw: Allow different devices on the same link If the current code encounters a new type of device on a SoundWire link, it will abort processing that link and move onto the next link. However, there is no reason to disallow this setup, it would appear this was being disallowed to work around issues introduced by only the first endpoint on each link being checked, which is now fixed. The device type shouldn't determine which DAI link it is connected to, the group ID and aggregation status should.
