[PATCH] nfc: s3fwrn5: make array match static const, reduces object code size

From: Colin King
Date: Tue Sep 19 2017 - 10:25:25 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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
