Miquel Raynal e7952f4d62 nvmem: core: Return NULL when no nvmem layout is found ... [ Upstream commit 81e1d9a395 ] Currently, of_nvmem_layout_get_container() returns NULL on error, or an error pointer if either CONFIG_NVMEM or CONFIG_OF is turned off. We should likely avoid this kind of mix for two reasons: to clarify the intend and anyway fix the !CONFIG_OF which will likely always if we use this helper somewhere else. Let's just return NULL when no layout is found, we don't need an error value here.
