[PATCH] drm/amd/amdgpu: use kmalloc_array instead of kmalloc

From: Moktar SELLAMI

Date: Mon Sep 22 2025 - 14:56:50 EST


Replace kmalloc -> kmalloc_array in drm/amd/amdgpu/amdgpu_ras.c .

As per said in the Documentation/process/deprecated.rst, dynamic size
calculation should not be performed in memory allocator function
arguments due to the risk of overflow.
