nfc: s3fwrn5: use signed integer for parsing GPIO numbers

2020-11-24T23:00:53+00:00

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.

nfc: s3fwrn5: Constify s3fwrn5_fw_info when not modified

2020-09-10T22:22:16+00:00

Two functions accept pointer to struct s3fwrn5_fw_info but do not
modify the contents.  Make them const so the code is a little bit safer.

nfc: s3fwrn5: Add missing CRYPTO_HASH dependency

2020-09-10T22:22:16+00:00

The driver uses crypto hash functions so it needs to select CRYPTO_HASH.
This fixes build errors:

  arc-linux-ld: drivers/nfc/s3fwrn5/firmware.o: in function `s3fwrn5_fw_download':
  firmware.c:(.text+0x152): undefined reference to `crypto_alloc_shash'

nfc: s3fwrn5: Remove wrong vendor prefix from GPIOs

2020-09-10T22:22:16+00:00

The device tree property prefix describes the vendor, which in case of
S3FWRN5 chip is Samsung.  Therefore the "s3fwrn5" prefix for "en-gpios"
and "fw-gpios" is not correct and should be deprecated.  Introduce
properly named properties for these GPIOs but still support deprecated
ones.

We got slightly different patches removing a double word
in a comment in net/ipv4/raw.c - picked the version from net.

Simple conflict in drivers/net/ethernet/ibm/ibmvnic.c. Use cached
values instead of VNIC login response buffer (following what
commit 507ebe6444a4 ("ibmvnic: Fix use-after-free of VNIC login
response buffer") did).
