   4 Subject: [PATCH] nvmem: Move of_nvmem_layout_get_container() in another header
   5
   6 nvmem-consumer.h is included by consumer devices, extracting data from
   7 NVMEM devices whereas nvmem-provider.h is included by devices providing
   8 NVMEM content.
   9
  10 The only users of of_nvmem_layout_get_container() outside of the core
  11 are layout drivers, so better move its prototype to nvmem-provider.h.
  12
  13 While we do so, we also move the kdoc associated with the function to
  14 the header rather than the .c file.
