I have a problem with this patch. It only fixes one of the regressions

Does the same problem also happen in Linus's tree? If not, any hints on
the patch that might have fixed it there?
Yes, it does. IMHO the entire patch (between 4.4 and 4.5 that broke user
land multiple ways) should be reverted and a fix for what ever obscure
BUG was supposed to be fixed should be "retried".
That's still an unresolved issue, and it's on my list to things to look
into.
This particular patch though fixes a different issue, and should be
applied to -stable.
This patch fixes a bug that was introduced to fix "some other obscure
BUG" that has nothing to do whatever with the "physical floppy" device.
And it broke user land in at least 2 ways. All this patch does is revert
part of the original patch so that it is only broke in 1 way to user
land. It should revert the whole thing IMHO.
Which patch is this? If that is truly the case, it should be reverted
asap.
