From 4a1a40233b4a9fc159a5c7a27dc34c5c7bc5be55 Mon Sep 17 00:00:00 2001 From: Miquel Raynal Date: Fri, 15 Dec 2023 11:15:28 +0000 Subject: [PATCH] nvmem: Move of_nvmem_layout_get_container() in another header nvmem-consumer.h is included by consumer devices, extracting data from NVMEM devices whereas nvmem-provider.h is included by devices providing NVMEM content. The only users of of_nvmem_layout_get_container() outside of the core are layout drivers, so better move its prototype to nvmem-provider.h. While we do so, we also move the kdoc associated with the function to the header rather than the .c file.
