If no write callback is given the device should be marked as read-only.
While at it also move from a bit or to a logical or as that is a logical

e the module and increment the reference count like it is done
in the DT path.
To fix this we replace the call to nvmem_find() with a call to
__nvmem_device_get() which does all the referencing and return a
proper ERR_PTR in case of error.

What is the real use-case here, it does not make sense to me to add this

It also return NULL when nvmem is not compiled in. I quiet like such
convenience functions as they make the driver code much s

Hi,
this series is mostly small bug fixes, but also add a new API
to make things simpler in drivers that need to request an optional cell.

The Spreadtrum SC27XX efuse data are organized by blocks and each block
contains 2 bytes data. Moreover the nvmem core always pass the offset
in byte to the controller, so we should change the offset in byte to
the correct block index
