I generally send a patches on single git-send command
git send-emal --to=ldewangan-DDmLM1+adcrQT0dZR+AlfA@public.gmane.org 0000.patch 0001.patch

So file names are in seq but not sure why it is not on seq. Something 
mail exchange  resuffle.
Probably I need to send one by one...

Some of the rails are not used in board and hence their inputs are also 
left floating (unconnected). In this case, during DT population, I did 
not put entry
i.e. if ldo1 is not used then ldo1-in is not connected on board and hence
entry on DT

ldo1-in-supply=<&xyzreg>;

is not there.

The regulator core register the regulator even if there is NULL 
init_data and in this case, it tries to findout the input-supply 
(provided through desc->supply_name) and it fails to find out the supply 
handle and so regulator register fails cause all regulator registration 
to fail.

So providing the dec->supply_name only in case of valid init_data.
