after cleanup voltage still on pin

[gek47]

Set pin pull to to UP and cleanup does set the bias to the correct state but voltage is still on the pin.
I was seeing odd behavior, so I check the pin with a VOM and shows 3.28 volts after cleanup.
If I call setbias(pin, GPIO_DISABLE) before cleanup no voltage.

Test setup is Raspberry PI 4B 4GB, Archlinux Arm aarch64 mainline kernel

$ uname -a
Linux landmine 5.19.8-1-aarch64-ARCH #1 SMP PREEMPT Thu Sep 8 18:20:33 MDT 2022 aarch64 GNU/Linu


import RPi.GPIO as GPIO
import time   

GPIO.setmode(GPIO.BCM)

print(f"PUD_OFF:  {GPIO.PUD_OFF}")
print(f"PUD_UP:   {GPIO.PUD_UP}")
print(f"PUD_DOWN: {GPIO.PUD_DOWN}")


TEST_PIN = 26
GPIO.setup(TEST_PIN, GPIO.IN, pull_up_down=GPIO.PUD_UP)

time.sleep(2)
print(f"before cleanup getbias: {GPIO.getbias(TEST_PIN)}")

print(f"before cleanup getdirection: {GPIO.getdirection(TEST_PIN)}")

GPIO.cleanup()

time.sleep(2)


time.sleep(2)
print(f"after cleanup getbias: {GPIO.getbias(TEST_PIN)}")

print(f"after cleanup getdirection: {GPIO.getdirection(TEST_PIN)}")


Output:
PUD_OFF:  1
PUD_UP:   3
PUD_DOWN: 4
before cleanup getbias: 3
before cleanup getdirection: 2
after cleanup getbias: 1
after cleanup getdirection: -1
