From: Michael Walle <michael@xxxxxxxx>
commit db3546d58b5a0fa581d9c9f2bdc2856fa6c5e43e upstream.
nvmem_add_cells() could return an error after some cells are already
added to the provider. In this case, the added cells are not removed.
Remove any registered cells if nvmem_add_cells() fails.
Fixes: fa72d847d68d7 ("nvmem: check the return value of nvmem_add_cells()")
