[PATCH 4.9 47/92] USB: adutux: remove redundant variable minor
From: Greg Kroah-Hartman
Date: Wed Oct 16 2019 - 18:17:12 EST
From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
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
