Subject: [PATCH] gyro:adis16136: fix debugfs_simple_attr.cocci warnings
Date: Sun,  7 Jan 2018 14:31:57 +0530	[thread overview]
Message-ID: <1515315717-3950-1-git-send-email-venkat.prashanth2498@gmail.com> (raw)

From: Venkat Prashanth B U <venkat.prashanth2498@gmail.com>

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().

Generated by: scripts/coccinelle/api/debugfs/debugfs_simple_attr.cocci
