Subject: PCI: pcie-qcom.c mismerge(?) in next-20260123

Hello,

It seems, there is a mismerge (?) in drivers/pci/controller/dwc/pcie-qcom.c
in next-20260123. The next tree silently reboots during the boot on
Qualcomm RB3 Gen2 board, so does commit e4cfff34b9ad ("Merge branch
'next' of https://git.kernel.org/pub/scm/linux/kernel/git/pci/pci.git").
Both of its parents boot successfully.
