Subject: [gcc-14 PATCH] drm: i915: Adapt to -Walloc-size GCC 14 introduces a new -Walloc-size included in -Wextra which errors out like: ``` drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c: In function ‘eb_copy_relocations’: drivers/gpu/drm/i915/gem/i915_gem_execbuffer.c:1681:24: error: allocation of insufficient size ‘1’ for type ‘struct drm_i915_gem_relocation_entry’ with size ‘32’ [-Werror=alloc-size] 1681 | relocs = kvmalloc_array(size, 1, GFP_KERNEL); | ^ ``` So, just swap the number of members and size arguments to match the prototype, as we're initialising 1 element of size `size`. GCC then sees we're not doing anything wrong.
