Subject: [PATCH v2 8/9] HID: introduce helper to access hid_output_raw_report()
Date: Wed,  5 Feb 2014 16:33:23 -0500	[thread overview]
Message-ID: <1391636004-29354-9-git-send-email-benjamin.tissoires@redhat.com> (raw)
In-Reply-To: <1391636004-29354-1-git-send-email-benjamin.tissoires@redhat.com>

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
