Subject: [PATCH 6/6] staging: comedi: Remove set but not used variable 'aref'
Date: Tue, 8 Oct 2019 13:39:02 +0800	[thread overview]
Message-ID: <1570513142-60177-7-git-send-email-zhengbin13@huawei.com> (raw)
In-Reply-To: <1570513142-60177-1-git-send-email-zhengbin13@huawei.com>

Fixes gcc '-Wunused-but-set-variable' warning:

drivers/staging/comedi/drivers/dt3000.c: In function dt3k_ai_insn_read:
drivers/staging/comedi/drivers/dt3000.c:511:27: warning: variable aref set but not used [-Wunused-but-set-variable]

It is not used since commit 2e310235ca8f ("staging:
comedi: dt3000: rename dt3k_ai_insn()")
