Subject: [PATCH] staging: ks7010: remove redundant variable eth_proto

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

Variable eth_proto is being assigned but is never used hence it is
redundant and can be removed.

Cleans up clang warning:
warning: variable 'eth_proto' set but not used [-Wunused-but-set-variable]
