Subject: [nvdimm PATCH 4/6] nvdimm: Remove empty if statement
Date: Wed, 10 Oct 2018 16:39:06 -0700	[thread overview]
Message-ID: <20181010233901.12228.21705.stgit@localhost.localdomain> (raw)
In-Reply-To: <20181010233428.12228.26106.stgit@localhost.localdomain>

This patch removes an empty statement from an if expression and promotes
the else statement to the if expression with the expression logic reversed.

I feel this is more readable as the empty statement can lead to issues if
any additional logic was ever added.
