Subject: x86/PCI: Remove unnecessary list_empty(&pci_root_infos) check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=3323ab8f7a2f8ffed9393388863bf17329077524;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

x86/PCI: Remove unnecessary list_empty(&pci_root_infos) check

list_for_each_entry() handles empty lists, so there's no need to check
whether the list is empty first.
