Subject: [PATCH 4.14 13/65] USB: adutux: remove redundant variable minor

From: Colin Ian King <colin.king@...onical.com>

commit 8444efc4a052332d643ed5c8aebcca148c7de032 upstream.

Variable minor is being assigned but never read, hence it is redundant
and can be removed. Cleans up clang warning:

drivers/usb/misc/adutux.c:770:2: warning: Value stored to 'minor' is
never read
