[PATCH v5 16/28] i2c: mux: Set adapter physical device
From: Herve Codina
Date: Fri Feb 27 2026 - 09:06:17 EST
For i2c muxes, the parent of the mux adapter device is the adapter
device the mux is connected to.
This parent is not the physical device related to the mux adapter.
Indeed, the physical device of the mux adapter is the mux device itself.
Fill the adap.physdev with the mux device.
