Ok. I will add it back, continuing the versions. Actually I purposely
restarted version number in this submission because the Hi6421 regulator
driver part has been accepted in v5, so this patchset is not inheriting
'exactly' to the previous ones. But seems I am thinking in a wrong way.
I will take this as my v7. And next patchset I send will be v8.
Thanks.

It is not used. I will remove dev from 'struct hi6421_pmic'.
Thanks.
