From f6c802a726aea43a2937763f13560c1fd170fae6 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sat, 24 Jul 2021 23:49:25 +0200 Subject: [PATCH] nfc: constify nfc_ops Neither the core nor the drivers modify the passed pointer to struct nfc_ops, so make it a pointer to const for correctness and safety.
