Wysocki" , Shawn Guo , Sascha Hauer , Pengutronix Kernel Team , Fabio Estevam , Wolfram Sang , Rob Herring , Saravana Kannan , Mark Brown , Len Brown , Andy Shevchenko , Daniel Scally , Heikki Krogerus , Sakari Ailus , Geert Uytterhoeven Cc: kernel-team@android.com, Wolfram Sang , linux-kernel@vger.kernel.org, imx@lists.linux.dev, linux-arm-kernel@lists.infradead.org, linux-i2c@vger.kernel.org, devicetree@vger.kernel.org, linux-spi@vger.kernel.org, linux-acpi@vger.kernel.org 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.
