Subject: [PATCH 5.10 103/158] platform/chrome: cros_ec_proto: dont show MKBP version if unsupported

From: Tzung-Bi Shih <tzungbi@...nel.org>

[ Upstream commit b36f0643ff14a2fb281b105418e4e73c9d7c11d0 ]

It wrongly showed the following message when it doesn't support MKBP:
"MKBP support version 4294967295".

Fix it.
