Subject: [PATCH v3 1/2] Revert "treewide: Fix probing of devices in DT overlays"
Date: Thu, 11 Apr 2024 16:56:21 -0700 [thread overview]
Message-ID: <20240411235623.1260061-2-saravanak@google.com> (raw)
In-Reply-To: <20240411235623.1260061-1-saravanak@google.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")
