[PATCH 0/4] Remove un-needed 'major' registration when alloc_disk(0) is used.

[NeilBrown]

When alloc_disk(0) is used, the ->major number is ignored and
irrelevant.  Yet several drivers register a major number anyway.

This series of patches removes the pointless registrations.  The pmem
driver also does this, but a patch has already been sent for that
driver.

Note that I am not in a position to test these beyond simple compile
testing.

Thanks,
NeilBrown
