X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=89b9e08f186a203c250872a663c9eab09cdc583a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

xen-platform: fix error return code in platform_pci_init()

Fix to return a negative error code from the error handling
case instead of 0, otherwise the error condition cann't be
reflected from the return value.
