- Subject: [PATCH] nvmem: Create a header for internal sharing
- Before adding all the NVMEM layout bus infrastructure to the core, let's
- move the main nvmem_device structure in an internal header, only
- available to the core. This way all the additional code can be added in
- a dedicated file in order to keep the current core file tidy.
