Subject: [PATCH] extcon: sm5502: remove redundant assignment to variable cable_type

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

The variable cable_type is being initialized with a value that
is never read and is being re-assigned a little later on. The
assignment is redundant and hence can be removed.

Addresses-Coverity: ("Unused value")
