X-Git-Tag: v4.6-rc1~135^2~5^5
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=3487c65659088c8205d8ab726b45469912271bbd;p=linux.git

PCI: rcar: Remove PCI_PROBE_ONLY handling

The PCIe rcar host driver is not used in system configurations requiring
the PCI_PROBE_ONLY flag to be set to prevent resources assignment,
therefore the driver code handling the flag can be removed from the kernel.
