Just as an extra blank line here and it should pass
Add a preserve_mmc parameter to the sdhost overlay that allows removing fragment@1 and fragment@2 (which disable mmc and mmcnr). This is needed on Compute Module when using gpios_22_27 mode, since disabling the other MMC interfaces would break WiFi on CM. Signed-off-by: zjzhao <zjzhao@edatec.cn>
