From: Bjorn Helgaas Date: Tue, 31 Jan 2017 22:36:32 +0000 (-0600) Subject: PCI: iproc: Use of_device_get_match_data() to simplify probe X-Git-Tag: v4.11-rc1~92^2~11^2~2 X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=e5c3b3e9f012b8862753a04f03c6e27344332718;p=karo-tx-linux.git PCI: iproc: Use of_device_get_match_data() to simplify probe The only way to call iproc_pcie_pltfm_probe() is to match an entry in iproc_pcie_of_match_table[], so match cannot be NULL. Use of_device_get_match_data() to retrieve the pcie->type. No functional change intended.
