[Intel-gfx] [PATCH v2 2/2] drm/i915/dsi: use gen7 prefix for the global DSI functions
Jani Nikula

Tue Jul 3 13:53:29 UTC 2018
Avoid confusion with the functions to be added for the new gen 11 DSI
implementation by renaming the current DSI functions. While at it,
permutate the words in the function names to make them all start with
"gen7_dsi" or "gen7_dsi_pll".
Leave the static functions as-is for now; they could be renamed later if
needed.
No functional changes.
