Subject: [PATCH v3 0/2] nvmem: use is_bin_visible callback

Hi Greg,

As suggested I managed to use is_bin_visible for the existing code
and also added few more checks for callbacks before setting
permissions on the file. Which also means that Thunderbolt case
for write-only should be fixed automatically with this patch.

As part of this cleanup it does not make any sense to keep
nvmem-sysfs.c and nvmem.h anymore, so move all the relevant
code to core.c

Changes since v2:
        - Remove nvmem_sysfs_get_groups()
        - remove nvmem-sysfs.c and nvmem.h and move all
        relevant code to core.c

Changes since v1:
	- Updated permissions setup logic as suggested by Greg
	- Added checks for callbacks.

Thanks,
Srini
