+From 94d41d2b670111855a361a35806ebac8d2444042 Mon Sep 17 00:00:00 2001

+Subject: i2c: core: Restore acpi_walk_dep_device_list() getting called after
+ registering the ACPI i2c devs
+
+Commit 21653a4181ff ("i2c: core: Call i2c_acpi_install_space_handler()
+before i2c_acpi_register_devices()")'s intention was to only move the
+acpi_install_address_space_handler() call to the point before where
+the ACPI declared i2c-children of the adapter where instantiated by
+i2c_acpi_register_devices().
+
+But i2c_acpi_install_space_handler() had a call to
+acpi_walk_dep_device_list() hidden (that is I missed it) at the end
+of it, so as an unwanted side-effect now acpi_walk_dep_device_list()
+was also being called before i2c_acpi_register_devices().
+
+Move the acpi_walk_dep_device_list() call to the end of
+i2c_acpi_register_devices(), so that it is once again called *after*
+the i2c_client-s hanging of the adapter have been created.
+
+This fixes the Microsoft Surface Go 2 hanging at boot.
+
+Fixes: 21653a4181ff ("i2c: core: Call i2c_acpi_install_space_handler() before i2c_acpi_register_devices()")
