Subject: [RESEND] NTB: hw: amd: fix an issue about leak system resources
Date:   Tue, 11 Aug 2020 09:59:57 +0800
Message-Id: <1597111197-28563-1-git-send-email-likaige@loongson.cn>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The related system resources were not released when pci_set_dma_mask(),
pci_set_consistent_dma_mask(), or pci_iomap() return error in the
amd_ntb_init_pci() function. Add pci_release_regions() to fix it.
