    drm/i915: Stop reporting error details in dmesg as well as the error-state
    
    As we already capture all the information from the registers into the
    error-state, also dumping that to dmesg just generates noise that upsets
    CI and users alike (and doesn't provide us with any more information).

Add a citation that killing off pr_err was deliberate.
