[PATCH v11 04/11] PCI: dwc: Move devm_pci_alloc_host_bridge() to the beginning of dw_pcie_host_init()

From: Frank Li
Date: Thu Mar 13 2025 - 11:40:55 EST


Move devm_pci_alloc_host_bridge() to the beginning of dw_pcie_host_init().
Since devm_pci_alloc_host_bridge() is common code that doesn't depend on
any DWC resource, moving it earlier improves code logic and readability.
