The resulting warnings look something like this: drivers/gpu/drm/i915/i915_debugfs.c: In function ‘i915_dump_lrc’: drivers/gpu/drm/i915/i915_debugfs.c:2103:6: warning: suggest explicit braces to avoid ambiguous ‘else’ [-Wparentheses] if (ctx != dev_priv->kernel_context) ^ even if the code itself is fine. Since the warning is fairly easy to avoid by adding a braces around the if-statement near the for_each_xyz() construct, do so, rather than disabling the otherwise potentially useful warning. (The if-then-else statements used in the "for_each_xyz()" constructs are designed to be inherently safe even with no braces, but in this case it's quite understandable that gcc isn't really able to tell that). This finally leaves the standard "allmodconfig" build with just a handful of remaining warnings, so new and valid warnings hopefully will stand out.
