Subject: [PATCH] usb: typec: ucsi: remove redundant assignment to variable num

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

Variable num is being assigned with a value that is never read, it is
assigned a new value later in a for-loop. The assignment is redundant
and can be removed.

Addresses-Coverity: ("Unused value")
