Subject: PCI: Fix pci_find_present
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=3c92c57af9a24a08b8d2f76650b1209239914fcd;p=openwrt%2Fstaging%2Fblogic.git

PCI: Fix pci_find_present

pci_find_present() is only matching the last item in the list of ids.

The break after the match is found only escapes the for loop, not the
while loop, so found gets reset to NULL on the next pass.
