[ Upstream commit f397bc0781553d01b4cdba506c09334a31cb0ec5 ]

If nvmem_add_one_cell() failed, the ownership of "child" (or "info.np"),
thus its OF reference, is not passed further and function should clean
up by putting the reference it got via earlier of_node_get().  Note that
this is independent of references obtained via for_each_child_of_node()
loop.

The nvmem-rcar-efuse driver can be compiled as a module. Add missing
MODULE_DEVICE_TABLE so it can be matched by modalias and automatically

 "Here are some small nvmem and fastrpc fixes that missed the cut-off to
  get into 6.17-final, due to me being slow in getting them out, my
  fault, not the maintainers of these subsystems :(

  Anyway, better late than never.  Changes included in here are:

   - nvmem fix for automatic module loading

   - fastrpc driver fixes for reported issues

  All of these have been in linux-next for weeks (4?) with no reported
  issues"

  nvmem: layouts: fix automatic module loading

To support loading of a layout module automatically the MODALIAS
variable in the uevent is needed. Add it.
