Unbeknownst to me, and unremarked upon by the checkpatch maintainer, this same problem was also solved in the mm tree. Fixing it once is enough, so this one comes out.

Note that due to the extreme simplicity of the scripting, any slightly more complex cases spread over multiple lines would not be triggered: they definitely exist, but this covers the vast bulk of the cases, and the resulting diff is also then easier to check automatically. For the same reason the 'flex' versions will be done as a separate conversion.

This makes it hard to read coccinelle's suggested changes, especially for someone new to coccicheck. From this commit, we warn about this behaviour from within the script on an unset debug file. Explicitly setting the debug file to /dev/null suppresses the warning while keeping the default.
