From ae72c9910b170e55386586cf18ef9015a8d172e6 Mon Sep 17 00:00:00 2001 From: Markus Elfring Date: Mon, 22 May 2017 14:11:01 +0200 Subject: NFC: digital: Improve a size determination in four functions Replace the specification of four data structures by pointer dereferences as the parameter for the operator "sizeof" to make the corresponding size determination a bit safer according to the Linux coding style convention.
