Subject: [PATCH] elevator: eliminate unused result build warning
Date: Wed, 10 May 2017 23:29:35 +0800	[thread overview]
Message-ID: <20170510152935.24968-1-yongming.yang@windriver.com> (raw)

Gcc complains about ignoring return value of ‘strstrip’; Fix it by
just using the strstrip() as the function parameter.
