In the Linux kernel, the following vulnerability has been resolved: drm/amdgpu: fix NULL pointer issue buffer funcs If SDMA block not enabled, buffer_funcs will not initialize, fix the null pointer issue if buffer_funcs not initialized.

A flaw was found in the Linux kernel's drm/amdgpu component. When the SDMA (System Direct Memory Access) block is not enabled, the buffer_funcs are not properly initialized. This can lead to a NULL pointer dereference, potentially causing a system crash and a denial of service.
