From 413fb0f81c527020ac3cede21bf7bfc332fde8cd Mon Sep 17 00:00:00 2001 From: Lucas Stach Date: Thu, 16 Jan 2020 12:19:20 +0800 Subject: [PATCH] nvmem: imx-ocotp: reset error status on probe [ Upstream commit c33c585f1b3a99d53920bdac614aca461d8db06f ] If software running before the OCOTP driver is loaded left the controller with the error status pending, the driver will never be able to complete the read timing setup. Reset the error status on probe to make sure the controller is in usable state.
