Subject: [PATCH] mtd: remove unused variable in mtdswap
Date: Tue, 25 Jul 2017 17:41:58 +0200
Message-Id: <20170725154208.355381-1-arnd@arndb.de>
Sender: linux-kernel-owner@vger.kernel.org
Content-Length: 907

The only user of this variable was removed, leading to a
new harmless warning:

drivers/mtd/mtdswap.c: In function 'mtdswap_add_debugfs':
drivers/mtd/mtdswap.c:1317:17: error: unused variable 'dev' [-Werror=unused-variable]

This removes the variable as well.

Fixes: e8e3edb95ce6 ("mtd: create per-device and module-scope debugfs entries")
