Subject: powerpc/pci: remove the multi-init for pci_dn->phb
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=145a2d0427a88e874f85e82e6fc42933a36f5a2b;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

powerpc/pci: remove the multi-init for pci_dn->phb

pci_dn->phb is set to phb in update_dn_pci_info(), if succeed.

This patch removes the duplication of pci_dn->phb initialization.
