[Intel-gfx] [PATCH] intel: properly test for HAS_LLC

[Daniel Vetter]

If the kernel supports the test, we need to check the param.
Copy&pasta from the above checks that only look at the return value.
Interesting how much one can get such a simple interface wrong.

    intel: query for LLC support

Patch even claims to have fixed this in v2, but is actually unchanged
from v1.
