Subject: [PATCH 01/16] Revert "treewide: Fix probing of devices in DT overlays"
From: Saravana Kannan <saravanak@...gle.com>
From: Saravana Kannan <saravanak@...gle.com>
This reverts commit 1a50d9403fb90cbe4dea0ec9fd0351d2ecbd8924.
While the commit fixed fw_devlink overlay handling for one case, it
broke it for another case. So revert it and redo the fix in a separate
patch.
Fixes: 1a50d9403fb9 ("treewide: Fix probing of devices in DT overlays")
