Subject: [-next PATCH 4/4] treewide: Use DEVICE_ATTR_WO
Convert DEVICE_ATTR uses to DEVICE_ATTR_WO where possible.
Done with perl script:
$ git grep -w --name-only DEVICE_ATTR | \
xargs perl -i -e 'local $/; while (<>) { s/\bDEVICE_ATTR\s*\(\s*(\w+)\s*,\s*\(?(?:\s*S_IWUSR\s*|\s*0200\s*)\)?\s*,\s*NULL\s*,\s*\s_store\s*\)/DEVICE_ATTR_WO(\1)/g; print;}'
