Subject: [PATCH][next] drivers: thermal: tsens: remove redundant u32 comparison with less than zero

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

The u32 variable hw_id is unsigned and cannot be less than zero so
the comparison with less than zero is always false and hence is redundant
and can be removed.

Addresses-Coverity: ("Unsigned compared against 0")
