If anyone has any objections, please let me know. ------------------ From: Pengpeng Hou [ Upstream commit 09a9e1746a87845d7d8e2b4e23bb613306effdff ] aspeed_pwm_tacho_probe() installs its reset cleanup action and configures the controller after an unchecked reset deassertion. Stop probing when the reset controller rejects the transition, before the hwmon device becomes visible.
