[BUG] EDID leaks kernel memory

Hi,

While looking at the kernel DRM code, I've noticed that in many places we kmalloc() memory to store the raw EDID information, whether it be from a DDC adapter, or loaded from firmware.

Nowhere can I find where this memory is freed. It seems in several places that we assign it into connector->display_info.raw_edid, and next time we obtain EDID information, we re-kmalloc and overwrite this pointer.

Note that some drivers do kfree() this memory themselves after blindly setting connector->display_info.raw_edid to NULL...

Can someone please point me to where this memory is freed? If not, I'll cook up a patch to add some kfree's.

Thanks.
