replying to myself after looking at the code;
I am almost certain it's this one:
https://cgit.freebsd.org/src/commit/sys/dev/sdhci/sdhci.c?id=a72af82e3169fcacfedf9047120679300a4296f8

Given the previous version did pass that:
https://cgit.freebsd.org/src/commit/sys?id=aeb04e88f51a706ef4b6a380bf5e82d15203fb6a
