Rahul Sharma 9c08e4ba81 drm/exynos: let drm handle edid allocations
There's no need to allocate edid twice and do a memcpy when drm helpers
exist to do just that. This patch cleans that interaction up, and
doesn't keep the edid hanging around in the connector.

v4:
- removed error check for drm_mode_connector_update_edid_property
which is expected to fail for Virtual Connectors like VIDI.
Thanks to Seung-Woo Kim.

v3:
- removed MAX_EDID as it is not used anymore.

v2:
- changed vidi_get_edid callback inside vidi driver.

************************************************************

************************************************************

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).

The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:

    1. The DRM provides synchronized access to the graphics hardware via
       the use of an optimized two-tiered lock.

    2. The DRM enforces the DRI security policy for access to the graphics
       hardware by only allowing authenticated X11 clients access to
       restricted regions of memory.

    3. The DRM provides a generic DMA engine, complete with multiple
       queues and the ability to detect the need for an OpenGL context
       switch.

    4. The DRM is extensible via the use of small device-specific modules
       that rely extensively on the API exported by the DRM module.


Documentation on the DRI is available from:
    http://dri.freedesktop.org/wiki/Documentation
