From 7186aac9c22de855220ebc54df7af399647bd1fc Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sat, 24 Jul 2021 23:49:28 +0200 Subject: [PATCH] nfc: constify nfc_digital_ops Neither the core nor the drivers modify the passed pointer to struct nfc_digital_ops, so make it a pointer to const for correctness and safety.
