Subject: [PATCH] mtd: remove unused variable in mtdswap

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")
Signed-off-by: Arnd Bergmann <arnd@...db.de>
