i2c: acpi: Unbind mux adapters before delete
There is an issue with ACPI overlay table removal specifically related to I2C multiplexers.
Consider an ACPI SSDT Overlay that defines a PCA9548 I2C mux on an existing I2C bus. When this table is loaded we see the creation of a device for the overall PCA9548 chip and 8 further devices - one i2c_adapter each for the mux channels. These are all bound to their ACPI equivalents via an eventual invocation of acpi_bind_one().
When we unload the SSDT overlay we run into the problem. The ACPI devices are deleted as normal via acpi_device_del_work_fn() and the acpi_device_del_list.
However, the following warning and stack trace is output as the deletion does not go smoothly: ------------[ cut here ]------------ kernfs: can not remove 'physical_node', no directory WARNING: CPU: 1 PID: 11 at fs/kernfs/dir.c:1674 kernfs_remove_by_name_ns+0xb9/0xc0 Modules linked in: CPU: 1 PID: 11 Comm: kworker/u128:0 Not tainted 6.8.0-rc6+ #1 Hardware name: congatec AG conga-B7E3/conga-B7E3, BIOS 5.13 05/16/2023 Workqueue: kacpi_hotplug acpi_device_del_work_fn RIP: 0010:kernfs_remove_by_name_ns+0xb9/0xc0 Code: e4 00 48 89 ef e8 07 71 db ff 5b b8 fe ff ff ff 5d 41 5c 41 5d e9 a7 55 e4 00 0f 0b eb a6 48 c7 c7 f0 38 0d 9d e8 97 0a d5 ff <0f> 0b eb dc 0f 1f 00 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 RSP: 0018:ffff9f864008fb28 EFLAGS: 00010286 RAX: 0000000000000000 RBX: ffff8ef90a8d4940…
