8a2151c587 NFC: pn544: use flags argument of devm_gpiod_get to set direction
Since 39b2bbe3d7 (gpio: add flags argument to gpiod_get*()
functions) which appeared in v3.17-rc1, the gpiod_get* functions
take an additional parameter that allows to specify direction and
initial value for output.

Use this to simplify the driver. Furthermore this is one caller less
that stops us making the flags argument to gpiod_get*() mandatory.

While touching this also do some minor coding style fixes.

ab714817d7 NFC: trf7970a: Handle extra byte in response to Type 5 RMB commands
The current versions of the trf7970a has an erratum where it returns
an extra byte in the response to 'Read Multiple Block' (RMB) commands.
This command is issued to Type 5 tags (i.e., ISO/IEC 15693 tags) by
the neard daemon.

To handle this, define a new Device Tree property,
't5t-rmb-extra-byte-quirk', which indicates that the associated
trf7970a device has this erratum.  The trf7970a device driver
will then ensure that the response length to RMB commands is
reduced by one byte (for devices with the erratum).

st21nfca_get_iso14443_3_uid() does not correctly copy the uid from

puts a pointer to uid_skb->data to the local variable gate.
This means that in st21nfca_hci_target_from_gate() the content
of "u8 uid[NFC_NFCID1_MAXSIZE]" local variable is never initialized
before being used in memcpy(target->nfcid1, uid, len).

Fix this by replacing the local variable assignment with a memcpy.

This was found by compiling Linux with
"gcc -Wunused-but-set-parameter".
