If anyone has any objections, please let me know. ------------------ From: Pengpeng Hou [ Upstream commit 95e4eb426b4bd666fa2f37886c0ddf74a0cc6167 ] aspeed_adc_probe() continues to register ADC resources after deasserting the shared reset, even if the reset controller reports a failure. A failed deassertion leaves the hardware unavailable, so stop probing before installing the cleanup action and enabling the ADC.
