[PATCH v4 06/21] platform/chrome: cros_ec_proto: use cros_ec_map_error()

From: Tzung-Bi Shih
Date: Thu Jun 09 2022 - 04:51:45 EST


Use cros_ec_map_error() in cros_ec_get_host_event_wake_mask().

The behavior of cros_ec_get_host_event_wake_mask() slightly changed. It
is acceptable because the caller only needs it returns negative integers
for indicating errors. Especially, the EC_RES_INVALID_COMMAND still
maps to -EOPNOTSUPP.
