Subject: NFC: trf7970a: FIFO Size is really 127 bytes
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=1568bfef18a9150d83b0f91aa254cef7ebead4cd;p=deliverable%2Flinux.git

NFC: trf7970a: FIFO Size is really 127 bytes

Despite what the manual says, the FIFO size
on the trf7970a is really 127 bytes so make
the code respect that.
