Subject: [PATCH 5.15 164/244] 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.
