CONFIG_DRM_I915_USERFAULT_AUTOSUSPEND is an int, defaulting to 250. When
the wakeref is non-zero, it's either -1 or a dynamically allocated
pointer, depending on CONFIG_DRM_I915_DEBUG_RUNTIME_PM. It's likely that
the code works by coincidence with the bitwise AND, but with
CONFIG_DRM_I915_DEBUG_RUNTIME_PM=y, there's the off chance that the
condition evaluates to false, and intel_wakeref_auto() doesn't get
called. Switch to the intended logical AND.
