Subject: [PATCH 4.19 68/93] typec: tcpm: fix a typo in the comparison of pdo_max_voltage

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

commit a684d8fd87182090ee96e34519ecdf009cef093a upstream.

There appears to be a typo in the comparison of pdo_max_voltage[i]
with the previous value, currently it is checking against the
array pdo_min_voltage rather than pdo_max_voltage. I believe this
is a typo. Fix this.
