Dumping the register may be useful for the debug level, I am not sure.
Maybe Adrian has an opinion?

As I said on patch1, please use pr_debug() and drop the macro.

If we really need this, I think we should first introduce the helper
function in a separate patch, that precedes $subject patch in the
series.

My understanding was that the original issue was that these messages
appear when it is not a UHS-II card, so the register dump should also
become debug-only.

Hi, Ulf
This macro has been defined in previous patches not the first time it
has appeared here,
are we still going to drop this macro?

Ok, I will make this helper function into a separate patch in the next version.
