[Intel-gfx] [PATCH] drm/i915: Force clean compilation with -Werror

[Chris Wilson]

Our driver compiles clean (nowadays thanks to 0day) but for me, at least,
it would be beneficial if the compiler threw an error rather than a
warning when it found a piece of suspect code. (I use this to
compile-check patch series and want to break on the first compiler error
in order to fix the patch.)
