SubjectNew warnings with gcc-11
I've updated to Fedora 34 on one of my machines, and it causes a lot
of i915 warnings like

drivers/gpu/drm/i915/intel_pm.c: In function ‘ilk_setup_wm_latency’:
drivers/gpu/drm/i915/intel_pm.c:3059:9: note: referencing argument 3
of type ‘const u16 *’ {aka ‘const short unsigned int *’}
drivers/gpu/drm/i915/intel_pm.c:2994:13: note: in a call to function

and the reason is that gcc now seems to look at the argument array
size more, and notices that

(a) intel_print_wm_latency() takes a "const u16 wm[8]" argument


(b) most of the arrays passed in tend to look like 'u16 pri_latency[5]'

I think I will make the argument type to intel_print_wm_latency() be
just "const u16 wm[]" for now, just to avoid seeing a ton of silly

I'm not sure if there is a better solution (like making all of those
latency arrays be 8 entries in size), so I'm just letting you know
about my change in this area in case anybody has a better idea.
