From cd31dae7e604621c3921699c930bb6f5e6bedb5d Mon Sep 17 00:00:00 2001 From: Philipp Guendisch Date: Thu, 13 Jul 2017 02:55:42 -0400 Subject: [PATCH] media: staging: atomisp: hmm: Fixed comment style This patch fixed comment style. Semantic should not be affected. There are also two warnings left about too long lines, which reduce readability if changed.
