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

From: Bartosz Golaszewski <bgolaszewski@...libre.com>

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@...el.com>
Fixes: 2a127da461a9 ("nvmem: add support for the write-protect pin")
