Hi, Looks like commit 5451781dadf8 ("regulator: core: Only count load for enabled consumers") started showing new warnings with v5.0-rc cycle: regulator-dummy: Underflow of regulator enable count I'm seeing this at least with my pwm-vibra test case: # rumble-test /dev/input/by-path/platform-vibrator-event 0xffff pwm-vibrator vibrator: vibrator supply vcc not found, using dummy regulator input: pwm-vibrator as /devices/platform/vibrator/input/input4 regulator-dummy: Underflow of regulator enable count Upload rumble effect... id=0 regulator-dummy: Underflow of regulator enable count Are these bogus warnings for dummy regulator or do we have real unpaired regulator calls or somewhere? Regards, Tony
