If anyone has any objections, please let me know. ------------------ From: LiangCheng Wang [ Upstream commit 0286324da660875dc504fd65b3be87e9c8b9a547 ] fsl_asoc_card_probe() hard-fails with -EINVAL when the CPU DAI (SAI) platform device is not found. Like the codec, the CPU DAI may just be probed later than the machine driver; the order is not guaranteed and varies across kernel versions, so a permanent -EINVAL leaves the card unregistered with no analog playback or capture. Defer probe instead, mirroring commit e396dec46c56 ("ASoC: fsl-asoc-card: Defer probe when fail to find codec device"). Tested on i.MX8MP with an ALC5672 on SAI3: the card that failed to register on v6.18 now comes up during boot.
