Use the helper function amdgpu_ip_block_suspend where
same checks and calls are repeated.
I strongly suggest to squash this patch and the next one together.
Sure. Noted

Please add "ip_blocks->status.hw = false;" and remove that from the
callers as well. I did not add that in the amdgpu_ip_block_suspendas
on failure we do return without setting status.hw=false. In case
suspend fail and we return then in that case as per the current logic
we dont set that flag. And with the current logic that is maintained.
Apart from that looks good to me, Christian.
