Subject: wil6210: fix debugfs_simple_attr.cocci warnings
X-Git-Tag: v4.20-rc1~27^2~83^2^2~6
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=f9dca154a4e4d185bad15a431f0ff095cd931df6;p=thirdparty%2Flinux.git

wil6210: 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().

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