For 0.85V cnl_get_buf_trans_edp() returns the DP table, instead of EDP.
Use the correct table.
The error was pointed out by this clang warning:
drivers/gpu/drm/i915/intel_ddi.c:392:39: warning: variable
'cnl_ddi_translations_edp_0_85V' is not needed and will not be emitted
[-Wunneeded-internal-declaration]
static const struct cnl_ddi_buf_trans cnl_ddi_translations_edp_0_85V[] = {

Looks like a typo in
cf54ca8 ("drm/i915/cnl: Implement voltage swing sequence.")
but Cc'ing Rodrigo, Clint to make sure this wasn't a workaround.

This makes sense, it should have returned the edp ddi buf translation
table as per the Bspec.
Please add this to the commit message:
Fixes: cf54ca8bc567 ("drm/i915/cnl: Implement voltage swing sequence.")

Yup, Like I mentioned in the previous reply, I am positive that this should
