Subject: [PATCH v2 4/4] libnvdimm/region: reduce an unnecessary if branch in nd_region_create()
Date: Wed, 19 Aug 2020 10:05:03 +0800	[thread overview]
Message-ID: <20200819020503.3079-5-thunder.leizhen@huawei.com> (raw)
In-Reply-To: <20200819020503.3079-1-thunder.leizhen@huawei.com>

The "else" branch can only be entered when ndr_desc->flush is NULL. After
replaced "NULL" with "ndr_desc->flush", we will find that the statements
in "if..else.." are the same.

No functional change.
