Subject: [PATCH] drm/radeon: Always call radeon_suspend_kms() in radeon_pci_shutdown()
Date:   Mon,  7 Jun 2021 20:27:00 +0800
Message-Id: <1623068820-2479-1-git-send-email-yangtiezhu@loongson.cn>
Precedence: bulk

radeon_suspend_kms() puts the hw in the suspend state (all asics),
it should always call radeon_suspend_kms() in radeon_pci_shutdown(),
this is a normal cleanup process to avoid more operations on radeon,
just remove #ifdef CONFIG_PPC64 and the related comments.
