I am trying to write a udev rule that will match a GPIO "chip" (not
a particular GPIO).
The device in question is:
# udevadm info -q all -p
/sys/devices/pci0000:00/0000:00:1f.0/gpio_ich.1.auto/gpio/gpiochip195
P: /devices/pci0000:00/0000:00:1f.0/gpio_ich.1.auto/gpio/gpiochip195
E:
DEVPATH=/devices/pci0000:00/0000:00:1f.0/gpio_ich.1.auto/gpio/gpiochip195
E: SUBSYSTEM=gpio
I am trying (unsuccessfully) to match it with this rule:
ACTION=="add",
DEVPATH=="/sys/devices/pci0000:00/0000:00:1f.0/gpio_ich.1.auto/gpio/gpiochip195",RUN+="/usr/sbin/modprobe
n5550_board"
When I load the gpio_ich module, I get this:

(I have also tried
DEVPATH=="/sys/devices/pci0000:00/0000:00:1f.0/gpio_ich.1.auto" with the
same lack of success.)
What am I doing wrong?
