Don't populate the read-only array match on the stack, instead make
it static const. Makes the object code smaller by over 310 bytes:
Before:
text data bss dec hex filename
8304 1084 128 9516 252c drivers/nfc/s3fwrn5/firmware.o
After:
text data bss dec hex filename
7894 1180 128 9202 23f2 drivers/nfc/s3fwrn5/firmware.o

i2c_device_id are not supposed to change at runtime. All functions
working with i2c_device_id provided by <linux/i2c.h> work with
const i2c_device_id. So mark the non-const structs as const.

A common pattern with skb_put() is to just want to memcpy()
some data into the new space, introduce skb_put_data() for
this.
An spatch similar to the one for skb_put_zero() converts many
of the places using it:
@@
identifier p, p2;
expression len, skb, data;
type t, t2;
@@
(
-p = skb_put(skb, len);
+p = skb_put_data(skb, data, len);
|
-p = (t)skb_put(skb, len);
+p = skb_put_data(skb, data, len);
)
(
p2 = (t2)p;
-memcpy(p2, data, len);
|
-memcpy(p, data, len);
)
@@
type t, t2;
identifier p, p2;
expression skb, data;

t *p;
...
(
-p = skb_put(skb, sizeof(t));
+p = skb_put_data(skb, data, sizeof(t));

-p = (t *)skb_put(skb, sizeof(t));
+p = skb_put_data(skb, data, sizeof(t));
)
(
p2 = (t2)p;
-memcpy(p2, data, sizeof(*p));

-memcpy(p, data, sizeof(*p));

(again, manually post-processed to retain some comments)

The s3fwrn5_phy_ops structure is never modified, so declare it as const.
Done with the help of Coccinelle.

Initially it was used to create hooks in the driver for
proprietary operations. Currently it is being used for hooks
for both proprietary and generic operations.

NFC_DEBUG is not defined in Kconfig and since DEBUG is not used
anywhere in this directory, we can safely remove this line.
