[PATCH linux-next] drm/i915/display: Remove unused variable and corresponding assignment

[luo penghao]

Variable is not used in functions, and its assignment is redundant too.
So it should be deleted.

The clang_analyzer complains as follows:

drivers/gpu/drm/i915/display/vlv_dsi.c:143:2 warning:

Value stored to 'data' is never read.
