From: Saravana Kannan Date: Mon, 11 May 2026 15:57:48 +0000 (+0200) Subject: Revert "treewide: Fix probing of devices in DT overlays" X-Git-Url: http://git.ipfire.org/gitweb/index.cgi?a=commitdiff_plain;h=aaf08c52df9a19148731d4a3cfd85d98455db901;p=thirdparty%2Fkernel%2Flinux.git Revert "treewide: Fix probing of devices in DT overlays" 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.
