drm/i915: Force clean compilation with -Werror
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 At this point, we applied it to the kernel and promptly kicked it out again as it broke buildbots (due to a compiler warning on 32bits): commit 908d759b210effb33d927a8cb6603a16448474e4 Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Tue May 26 07:46:21 2015 +0200 Revert "drm/i915: Force clean compilation with -Werror" v3: Avoid enabling -Werror for allyesconfig/allmodconfig builds, using COMPILE_TEST as a suitable proxy suggested by Andrew Morton. (Damien) Only make the option available for EXPERT to reinforce that the option should not be casually enabled.
