From 5c739e77ca338a37765370290e02cb270651380b Mon Sep 17 00:00:00 2001 From: Andre Guedes Date: Fri, 24 Apr 2020 13:16:23 -0700 Subject: [PATCH] igc: Remove igc_nfc_rule_exit() During igc_down(), we call igc_nfc_rule_exit() which traverse the NFC rule list disabling filters one by one. Later on in igc_down() flow we issue an hardware reset which also clear all filters. Since we already reset the hardware, we don't actually need to disable each filter manually. In order to simplify the code, this patch removes igc_nfc_rule() altogether.
