From cc5bdd323dde6494623f3ffe3a5b887fa21cd375 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Mon, 6 Feb 2023 13:43:48 +0000 Subject: [PATCH] nvmem: core: drop the removal of the cells in nvmem_add_cells() If nvmem_add_cells() fails, the whole nvmem_register() will fail and the cells will then be removed anyway. This is a preparation to introduce a nvmem_add_one_cell() which can then be used by nvmem_add_cells(). This is then the same to what nvmem_add_cells_from_table() and nvmem_add_cells_from_of() do.
