Subject: [PATCH] nvmem: set nvmem->owner to nvmem->dev->driver->owner if unset
All nvmem drivers are supposed to set the owner field of struct
nvmem_config, but this matches nvmem->dev->driver->owner.
As far as I see in drivers/nvmem/ directory, all the drivers are
the case. So, make nvmem_register() set the nvmem's owner to the
associated driver's owner unless nvmem_config sets otherwise.
Remove .owner settings in the drivers that are now redundant.
