[PATCH v2] drm/i915: Return correct EDP voltage swing table for 0.85V

Show all headers | View raw

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[] = {
