Commit 39bf4de89ff7 ("drm/i915: Add -Wall -Wextra to our build, set warnings to full") enabled extra warnings for i915 to spot possible bugs in new code, and then disabled a subset of these warnings to keep the current code building without warnings (with gcc). Enabling the extra warnings also enabled some additional clang-only warnings, as a result building i915 with clang currently is extremely noisy. For now also disable the clang warnings sign-compare, sometimes-uninitialized, unneeded-internal-declaration and initializer-overrides. If desired they can be re-enabled after the code has been fixed.
