[PATCH] net/hamradio/6pack: remove redundant variable channel

From: Colin King
Date: Thu Jul 05 2018 - 06:11:15 EST


From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

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

Cleans up two clang warnings:
warning: variable 'channel' set but not used [-Wunused-but-set-variable]
