Commit 2b9aef6fcd96ba7ed8c1ee723e391901852d344c introduced a regression:
checkpatch.pl started complaining about the following valid pattern:
do {
/* something */
} while (condition);
Fix the script to once again permit this pattern.

v2: correct inappropriate patch description.
v3: put version description under Signed-off-by line.
