From 17eb18d674d586e609a3e268975edd728d5c84a3 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Sat, 21 Oct 2017 01:57:42 +0900 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.
