Subject: [PATCH v2 0/5] dax-device: Some cleanups

Hello,

I didn't get any feedback for the (implicit) v1 of this series that
started with Message-Id: 20210127230124.109522-1-uwe@...ine-koenig.org,
but I identified a few improvements myself:

 - Use "dax-device" consistently as a prefix
 - Instead of requiring a .remove callback, make it explicitly
   optional. (Drop checking for .remove from former patch 1, introduce
   new patch "Properly handle drivers without remove callback")
 - The new patch about remove being optional allows to simplify one of
   the two dax drivers which is implemented in patch 4
 - Patch 5 got a bit smaller because we now have one driver less with a
   remove callback.
 - Added Andrew to To: as he merged dax drivers in the past.

Andrew: Assuming you consider these patches useful, would you please
care for merging them?

Best regards
Uwe
