Subject: [PATCH v5 5/5] iio:temperature:mlx90632: Some stylefixing leftovers
Date: Thu, 13 Aug 2020 09:51:25 +0200	[thread overview]
Message-ID: <20200813075125.4949-6-cmo@melexis.com> (raw)
In-Reply-To: <20200813075125.4949-1-cmo@melexis.com>

There is some inconsistency and whitespace cleanup performed in this
patch. It was done on top of my other patches, but I can rebase to head
of the togreg branch if it would go in sooner.
