drm/i915: Force clean compilation with -Werror (118182e9) · Commits · 戴 / test

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.) v2: Kick off a new "Debugging" submenu for i915.ko Signed-off-by:
