[PATCH v2 8/9] HID: introduce helper to access hid_output_raw_report()
From: Benjamin Tissoires
Date: Wed Feb 05 2014 - 16:35:19 EST
Add a helper to access hdev->hid_output_raw_report().
To convert the drivers, use the following snippets:
for i in drivers/hid/*.c
do
sed -i.bak "s/[^ \t]*->hid_output_raw_report(/hid_output_raw_report(/g" $i
done
Then manually fix for checkpatch.pl
