checkpatch: Add --strict messages for blank lines around braces
Blank lines around braces are not unnecessary. Emit a message on the use of these blank lines only when using --strict. int foo(int bar) { something or other.... } is generally written in the kernel as: int foo(int bar) { something or other... } Signed-off-by: Joe Perches <joe@perches.com> Cc: Andy Whitcroft <apw@canonical.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
