[ Upstream commit d8f0a86795c69f5b697f7d9e5274c124da93c92d ]
GPIOs - as returned by of_get_named_gpio() and used by the gpiolib - are
signed integers, where negative number indicates error. The return
value of of_get_named_gpio() should not be assigned to an unsigned int
because in case of !CONFIG_GPIOLIB such number would be a valid GPIO.
Fixes: c04c674fadeb ("nfc: s3fwrn5: Add driver for Samsung S3FWRN5 NFC Chip")
