Did you see, that there was a v1 of this series? There wasn't many
changes for these three patches. Just what Tudor mentioned that the
unsupported RDSFDP opcode should be mentioned in the commit message,
too.

Apart from that, the series now includes fixes that Sashiko found,
that is, the rollback in case of a failed SFDP parsing is broken. I
can also rebase that on top of these three patches.
