You no longer need any parameters for this function, right?
no we do not need that, I can update that in next version.


Also, you really don't even need the function, just point to the
variable instead.
We have a use case where in the user can chose to not have sysfs entry, specially if we have hypervisor trapping access to some range of entries in nvmem. This is enforced using CONFIG_NVMEM_SYSFS option.

Currently in upstream we have a stub function when CONFIG_NVMEM_SYSFS is not selected returning NULL.

If we want to remove this function and subsequently the nvmem-sysfs.c file then we have to have #ifdef in the code which am okay to do if that is something that you are keen on.
