[Nouveau] nouveau_subdev & misc patches

[Emil Velikov]

Hello all, this series includes a wide range of fixes - from a few
month's old one-liners from Andreas Heider regarding vga_switcheroo, via a
null pointer dereference and double memory allocation, to a buffer overflow.

Please review and comment
