<pre>commit c7fb3c6c1893fddbbd39e13066489050c29397c1

drm/i915: Use sseu size for determining eu_regs[]
eu_regs[] is written 2*max_slices times (like s_reg[]) but oddly read
2*max_slices + max_subslices/2 times. Allocate the array large enough
for the writes to avoid overwriting our stack and worry about the logic
later.
Fixes: 7aa0b14ede64 ("drm/i915: Remove variable length arrays from sseu
debugfs printers")
