Well, this is absoloutely right, the behaviour to clear blk_size
when dev->sizes
is NULL looks sensible to me. But seven lines below it says
-unconditionaly-:
blk_size[dev->major] =3D NULL;
Ah, yes. This second assignment can just be deleted, I suppose.

[In the good old days it wasn't there. It was added in 1.3.19,
don't know why, probably as a safeguard to make sure nobody
used these values while they are being set up. But someone
was bit by the assignment, since it is not undone if we take
the return, so in 2.3.48 the assignment was moved past the
return, with a conditional assignment before it. I believe
you are right, and we only want the conditional assignment.]
