[PATCH] nvmem: only build nvmem_find_cell_by_index() if OF is enabled

[PATCH] nvmem: only build nvmem_find_cell_by_index() if OF is enabled

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bgolaszewski@baylibre.com>

The following warning is produced when building nvmem core if
CONFIG_OF is disabled:

drivers/nvmem/core.c:496:1: warning: 'nvmem_find_cell_by_index' defined but not used [-Wunused-function]
 nvmem_find_cell_by_index(struct nvmem_device *nvmem, int index)
 ^~~~~~~~~~~~~~~~~~~~~~~~

This is caused by the fact that the only caller of this routine is
under an ifdef depending on this option. Fix it by adding a relevant
ifdef to the function in question as well.

You should probably attribute the function with "__maybe_unused"
Instead of adding this condition.

Sounds better indeed. I'll resend tomorrow to avoid spamming.

No "reported-by:" lines on this and the other patch?

Not nice :(
