    Subject[PATCH 5.9 635/757] NTB: hw: amd: fix an issue about leak system resources
    Date
    From: Kaige Li <likaige@loongson.cn>

    [ Upstream commit 44a0a3c17919db1498cebb02ecf3cf4abc1ade7b ]

    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.

    Fixes: a1b3695820aa ("NTB: Add support for AMD PCI-Express Non-Transparent Bridge")
