Move this and the other platform device pointer at the top of the file after the
enum declarations. They don't look nice in the middle of nowhere.

This doesn't look related to this patch. Should it be a different commit ?
And I just saw definition of nvmem_cell_read() and it says the returned buffer
must be freed by caller using kfree(). I dont' see you doing that. Please also
check if any other such resources are there which you forgot to free.

Again, stuff like this can't go in this patch itself. It is a separate
bug fix and you should send it with a matching fixes tag separately.
