From: "Tobin C. Harding" <me@xxxxxxxx> Subject: checkpatch: add sub routine get_stat_real() checkpatch currently contains duplicate code. We can define a sub routine and call that instead. This reduces code duplication and line count. Add subroutine get_stat_real() Link: http://lkml.kernel.org/r/1519700648-23108-2-git-send-email-me@xxxxxxxx Signed-off-by: Tobin C.
