Subject: PCI: eliminate double kfree in intel-iommu initialization
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=ece6763419f44ed72f4fc78752e5f5364df1794b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

PCI: eliminate double kfree in intel-iommu initialization

The destination of goto error also does a kfree(g_iommus), so it is not
correct to do one here.

This was found using Coccinelle (http://www.emn.fr/x-info/coccinelle/).
