## Description

In the Linux kernel, the following vulnerability has been resolved:  drm/amdgpu/ras: add ras_suspend callback and use it for cp_ecc_error_irq  cp_ecc_error_irq is acquired in amdgpu_gfx_ras_late_init() but released in gfx_v9_0_hw_fini(), so the put site has to query amdgpu_irq_enabled() because the get is skipped on SR-IOV VF.  ras_late_init / ras_fini have no suspend counterpart, so move the put to amdgpu_gfx_ras_suspend() / amdgpu_gfx_ras_fini() and add a matching ras_suspend callback that is invoked from amdgpu_ras_suspend() before disable_all_features().  The get and put now sit in the same place and check the same condition (not VF, funcs registered), no refcount querying needed.  An active flag gates ras_fini so the suspend-then-unload-without-resume path falls into amdgpu_ras_block_late_fini_default() instead of double-releasing what ras_suspend already cleaned up.  Drop the cp_ecc_error_irq put from gfx_v9_0_hw_fini().  gfx_v8_0 manages cp_ecc_error_irq locally and is unaffected; no other GFX generation has this IRQ.
