This function is a bool type where we are supposed to return false on
failure and true on success.  Negative error codes are currently treated
as true.

Fixes: a1b2278e4dfc ("drm/i915: skylake panel fitting using shared scalers")

You can drop the braces, too.

Multi-line indents get braces for readability.
