There is a previous check to on has_aliasing_ppgtt that returns 0 if it is false, so it is impossible for has_aliasing_ppgtt to be false on the final return of function intel_sanitize_enable_ppgtt, so final return in the function always will return 1. Hence the redundant ternary operator can be replaced with a return 1.

Thanks, I took it a few steps further and removed the variable altogether. I Cc'd you on the patch.

Yep, it's an improvement on my fix. Thanks for sorting that out.
