Subject: blkid: add curly braces to do-while statement
X-Git-Tag: v2.30-rc1~186

blkid: add curly braces to do-while statement

Some say people read do-while statements are easily as while statements and
get wrong impression.  This happens because do-whiles are not common.
Adding braces should make it easier to read the code.
