    i2c: aspeed: Fix the dummy irq expected print · ac168d67
    Tommy Huang authored
    When the i2c error condition occurred and master state was not
    idle, the master irq function will goto complete state without any
    other interrupt handling. It would cause dummy irq expected print.
    Under this condition, assign the irq_status into irq_handle.
    
    For example, when the abnormal start / stop occurred (bit 5) with
    normal stop status (bit 4) at same time. Then the normal stop status
    would not be handled and it would cause irq expected print in
    the aspeed_i2c_bus_irq.
    
    ...
    aspeed-i2c-bus x. i2c-bus: irq handled != irq.
    Expected 0x00000030, but was 0x00000020
    ...
