Hi all,

After merging the nvmem tree, today's linux-next build (i386 defconfig)
failed like this:

/home/sfr/next/next/drivers/nvmem/core.c: In function 'nvmem_cell_put':
/home/sfr/next/next/drivers/nvmem/core.c:1603:9: error: implicit declaration of function 'nvmem_layout_module_put' [-Werror=implicit-function-declaration]
 1603 |         nvmem_layout_module_put(nvmem);
      |         ^~~~~~~~~~~~~~~~~~~~~~~

Caused by commit

  ed7778e43271 ("nvmem: core: Rework layouts to become regular devices")

I have applied the following patch for today.
