Summary
drm/amdgpu: Fix potential out-of-bounds access in 'amdgpu_discovery_reg_base_init()'
Details

In the Linux kernel, the following vulnerability has been resolved:

drm/amdgpu: Fix potential out-of-bounds access in 'amdgpudiscoveryregbaseinit()'

The issue arises when the array 'adev->vcn.vcnconfig' is accessed before checking if the index 'adev->vcn.numvcn_inst' is within the bounds of the array.

The fix involves moving the bounds check before the array access. This ensures that 'adev->vcn.numvcninst' is within the bounds of the array before it is used as an index.

Fixes the below: drivers/gpu/drm/amd/amdgpu/amdgpudiscovery.c:1289 amdgpudiscoveryregbaseinit() error: testing array offset 'adev->vcn.numvcn_inst' after use.
