3 # The pcie-controller device was renamed to pcie in Linux kernel 4.14
4 # commit 28fbb9c539e2 ("ARM: dts: marvell: fix PCI bus dtc warnings").
5 # This script migrates the path in the UCI configuration from the old
6 # name to the new name and also back, when am upgrade or downgrade is
7 # done. It checks if the name exists before changing the configuration.
8 # This has to be done before the 10-wifi-detect script from mac80211 is
9 # executed because this would add the devices again under the new path
10 # name.
