[PATCH -next] nvmem: fix a 'makes pointer from integer without a cast' build warning

[Bartosz Golaszewski]

From: Bartosz Golaszewski <bgolaszewski@xxxxxxxxxxxx>

nvmem_register() returns a pointer, not a long int. Use ERR_CAST() to
cast the struct gpio_desc pointer to struct nvmem_device.

Reported-by: kbuild test robot <lkp@xxxxxxxxx>
Fixes: 2a127da461a9 ("nvmem: add support for the write-protect pin")
