Arnd Bergmann 014d15b8f3 drm/amdgpu: avoid integer overflow warning in amdgpu_device_resize_fb_bar() ... [ Upstream commit 822130b5e8 ] On 32-bit architectures comparing a resource against a value larger than U32_MAX can cause a warning: drivers/gpu/drm/amd/amdgpu/amdgpu_device.c:1344:18: error: result of comparison of constant 4294967296 with expression of type 'resource_size_t' (aka 'unsigned int') is always false [-Werror,-Wtautological-constant-out-of-range-compare] res->start > 0x100000000ull) ~~~~~~~~~~ ^ ~~~~~~~~~~~~~~ As gcc does not warn about this in dead code, add an IS_ENABLED() check at the start of the function. This will always return success but not actually resize the BAR on 32-bit architectures without high memory, which is exactly what we want here, as the driver can fall back to bank switching the VRAM access.
