From 1a2b3666da582f93635a9c7be663d8100b9a303f Mon Sep 17 00:00:00 2001 From: Fengguang Wu Date: Thu, 14 Dec 2017 16:39:05 +0100 Subject: [PATCH] mt76: fix debugfs_simple_attr.cocci warnings drivers/net/wireless/mediatek/mt76/debugfs.c:36:0-23: WARNING: fops_regval should be defined with DEFINE_DEBUGFS_ATTRIBUTE Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE for debugfs files. Semantic patch information: Rationale: DEFINE_SIMPLE_ATTRIBUTE + debugfs_create_file() imposes some significant overhead as compared to DEFINE_DEBUGFS_ATTRIBUTE + debugfs_create_file_unsafe().
