Subject: [PATCH] mt76: fix debugfs_simple_attr.cocci warnings
Date: Thu, 2 Feb 2017 15:06:10 +0100 (CET) [thread overview]
Message-ID: <alpine.DEB.2.20.1702021504380.3104@hadrien> (raw)
Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE
for debugfs files.
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
