Subject: [PATCH] drm/amd/amdgpu: use kmalloc_array instead of kmalloc
Date: Mon, 22 Sep 2025 19:56:35 +0100 [thread overview]
Message-ID: <20250922185635.50828-1-smokthar925@gmail.com> (raw)
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.
