Subject: [PATCH AUTOSEL 6.9 10/15] platform/chrome: cros_usbpd_logger: provide ID table for avoiding fallback match

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

[ Upstream commit e0e59c5335a0a038058a080474c34fe04debff33 ]

Instead of using fallback driver name match, provide ID table[1] for the
primary match.
