[Intel-gfx] [PATCH] drm/i915: Make intel_dsi_init() return void

[Damien Lespiau]

Functions that can't fail are such a bliss to work with, it'd be shame
to miss the occasion. The "failure" mode is the DSI connector not being
created, the rest of the initialization can carry on happily.

We weren't even checking that value anyway.
