    mips: cm: reprime error cause · d93fdf44

    commit 05dc6001af0630e200ad5ea08707187fe5537e6d upstream.
    
    Accordingly to the documentation
    ---cut---
    The GCR_ERROR_CAUSE.ERR_TYPE field and the GCR_ERROR_MULT.ERR_TYPE
    fields can be cleared by either a reset or by writing the current
    value of GCR_ERROR_CAUSE.ERR_TYPE to the
    GCR_ERROR_CAUSE.ERR_TYPE register.
    ---cut---
    Do exactly this. Original value of cm_error may be safely written back;
    it clears error cause and keeps other bits untouched.
    
    Fixes: 3885c2b4 ("MIPS: CM: Add support for reporting CM cache errors")
