From 9aaea09b4cbdbe1a80ab3fa1a5d32c3ec61fa6e2 Mon Sep 17 00:00:00 2001 From: Venkat Prashanth B U Date: Sun, 7 Jan 2018 14:31:57 +0530 Subject: gyro:adis16136: 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().
