[Intel-gfx] [PATCH] drm/i915: fix build issue when using clang

[Tong Zhang]

drm/i915 target adds some extra cflags, especially it does re-apply -Wall.
In clang this will override -Wno-format-security and cause the build to
fail when CONFIG_DRM_I915_WERROR=y. While with GCC this does not happen.
We reapply -Wno-format-security here to get around this issue.

For what it's worth, GCC would warn in the exact same way if
-Wformat-security was included within -Wall like it is for clang:

drivers/gpu/drm/i915/gt/intel_gt.c: In function ‘intel_gt_invalidate_tlbs’:
drivers/gpu/drm/i915/gt/intel_gt.c:988:9: error: format not a string literal and no format arguments [-Werror=format-security]

      |                         ^~~~~~~~~
cc1: all warnings being treated as errors

If fixing these warnings instead of just disabling the warning is
undesirable (since I feel like the entire point of the i195 cflags
situation is to enable more warnings than the main Makefile), I think
the commit message should be rewritten to something along the lines of:

"drm/i915 adds some extra cflags, namely -Wall, which causes
instances of -Wformat-security to appear when building with clang, even
though this warning is turned off kernel-wide in the main Makefile:"

"This does not happen with GCC because it does not enable
-Wformat-security with -Wall. Disable -Wformat-security within the i915
Makefile so that these warnings do not show up with clang."

The actual diff itself looks fine to me.

Thank you Nathan!
I will send a v2 with a revised commit message.

[Intel-gfx] [PATCH v2] drm/i915: fix build issue when using clang

[Tong Zhang]

drm/i915 adds some extra cflags, namely -Wall, which causes
instances of -Wformat-security to appear when building with clang, even
though this warning is turned off kernel-wide in the main Makefile:

This does not happen with GCC because it does not enable
-Wformat-security with -Wall. Disable -Wformat-security within the i915
Makefile so that these warnings do not show up with clang.

Given this is not enabled for GCC and it is disabled in the main
Makefile:

Reviewed-by: Nathan Chancellor <nathan@kernel.org>

Additionally, it seems like trace_printk() is designed to be able to
take a string literal without a format argument, so this should be fine.
