I think you should take care of including <linux/device/driver.h>
instead of depending on module_nvmem_layout_driver() *callers* to do
that.
That would help avoiding errors like:
In file included from drivers/nvmem/layouts/fixed.c:5:
./include/linux/nvmem-provider.h:252:2: warning: data definition has no
type or storage class
252 | module_driver(__layout_driver, nvmem_layout_register, \
| ^~~~~~~~~~~~~
./include/linux/nvmem-provider.h:252:2: error: type defaults to 'int' in
declaration of 'module_driver' [-Werror=implicit-int]
252 | module_driver(__layout_driver, nvmem_layout_register, \
| ^~~~~~~~~~~~~
