That's the case of, for instance: /sys/bus/i2c/drivers/CHT Whiskey Cove PMIC/unbind This one is not present under /sys/bus/pci: $ find /sys/bus/pci -name 'CHT Whiskey Cove PMIC' Although clearly this is provided by a PCI driver: /sys/devices/pci0000:00/0000:00:02.0/i2c-4/subsystem/drivers/CHT Whiskey Cove PMIC/unbind So, add an altertate What location in order to match bind/unbind to such devices.
