Subject: [PATCH] ALSA: ens137x: remove redundant variable result

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

Variable result is being assigned a value from a calculation
however the variable is never read, so this redundant variable
can be removed.

Cleans up clang warning: Value stored to 'result' is never read
