From 703d667a0cdf6dfa402c08e72d0c77a257ca5009 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Rafa=C5=82=20Mi=C5=82ecki?= Date: Tue, 19 Jul 2022 06:22:31 +0200 Subject: [PATCH] kernel: switch back to fw_devlink=permissive MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit This reverts commit 5356462ce54734afd32fce83ad118c58cfeb2a55. Kernel switching to fw_devlink=on as default broke probing some devices. Revert it until we get a proper fix. It seemed that mtd OF_POPULATED hack resolved probing issues but apparently not all of them. We got reports about reading MAC using NVMEM not working and USB controllers not working.
