From 29760c8e6d3a3d02a23439f62b7e663e0c38eb3b Mon Sep 17 00:00:00 2001 From: Mathew McBride Date: Mon, 7 Aug 2023 01:41:08 +0000 Subject: [PATCH] board: ten64: add missing error checks for retimer power on The retimer reset/power on logic was changed in a recent commit, however, it neglected to check if the commands sent to the board microcontroller (to control power to the retimer chip) actually completed. Add return checks for these operations so any failures will be reported to the user.
