Subject: pci: ensure enumeration of all devices in pci_init
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=60ee60944bd80c76939e90b8a39430e05b9059a8;p=u-boot.git

pci: ensure enumeration of all devices in pci_init

Use the uclass_first_device_check and uclass_next_device_check functions
instead of uclass_first_device and uclass_next_device in pci_init. This
ensures that all PCI devices are tried to be probed. Currently if a
device fails to probe, the enumeration stops and the devices which come
after the failed device are not probed.
