If anyone has any objections, please let me know. ------------------ From: Javier Carrasco [ Upstream commit d1ce827a9cc11ffdfec77b7fec9b73a8020a308d ] cc2_enable() returns early when the regulator is already enabled. This can happen if a previous regulator_disable() failed or if the regulator was configured as always-on. In this case, process_irqs remains false, causing the ready interrupt to be ignored. Subsequent operations waiting for the ready completion then time out. Set process_irqs before returning when the regulator is already enabled, so that the driver continues to process ready interrupts.
