[PATCH 12/15] drm: Use a flexible array member for blob property data

[ville.syrj...@linux.intel.com]

From: Ville Syrj?l? <ville.syrj...@linux.intel.com>

The blob property data is always allocated immediately after the object
header. No need for the extra indirection when accessing it, just use
a flexible array member.
