This patch fixes the following checkpatch warnings:

ERROR:OPEN_BRACE: open brace '{' following struct go on the same line
ERROR:TRAILING_STATEMENTS: trailing statements should be on next line [*]
WARNING:LINE_SPACING: Missing a blank line after declarations
WARNING:BLOCK_COMMENT_STYLE: Block comments use a trailing */ on a separate line
WARNING:BLOCK_COMMENT_STYLE: Block comments use * on subsequent lines
CHECK:BRACES: Blank lines aren't necessary after an open brace '{'
CHECK:LINE_SPACING: Please don't use multiple blank lines
