Message-ID: <20200828063403.3995421-1-yangyingliang@huawei.com> (raw)
config GENERIC_IOMAP is not selected on some arch, pci_iounmap()
don't implement, when we using pci_iomap/pci_iounmap, it will
lead to memory leak.
This patch set moves the implemention of pci_iounmap() to
lib/pci_iomap.c to fix this.
