From 1ff85bfa1614df6cacec780cd5922dc0b1c340c7 Mon Sep 17 00:00:00 2001 From: YueHaibing Date: Fri, 28 Dec 2018 07:33:35 +0000 Subject: [PATCH] HSI: omap_ssi_port: fix debugfs_simple_attr.cocci warnings 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().
