That is true in general, but does not apply to the two warnings in
question here. One warning checks for a hypothetical hardware problem
and the other warning could happen for several reasons, not only a
firmware bug.
It would make sense to put a warning in the respective places where a
firmware problem is detected, though. The parse_ioapics_under_ir()
function is a candidate where it would make sense, for example. But in
the error path of the intel_enable_irq_remapping() function a pr_warn
would do the same job.
