Why not have a different label for the two cases? That would make the
code easier to statically analyze, and perhaps be more understandable as
well.

I think You are right. So it could be better like this?

Or it could return right after allocation fails so there needn't be
goto. It is simplier, but maybe worse looking and to read. What is your
opinion?

Perhaps it is also pointless to call kfree on something that is known to
be NULL. But I think that there is quite some code that does that, so
others might have another opinion.

I guess there is also a point at which idata has been successfully
allocated but idata->buf has not.

And? kfree() simple ignores NULL pointers.
I would prefer to see previous version of patch, but let maintainer to choose.

Unnecessarily calling a function suggests that calling that function is
necessary when it is not. But it is probably not a big deal, especially
for a well known function like kfree.

Thanks, I've pushed this version of the patch to mmc-next.
