Subject: PCI: dra7xx: Use generic DesignWare accessors
X-Git-Tag: v4.9-rc1~32^2^4~3
X-Git-Url: https://asedeno.scripts.mit.edu/gitweb/?a=commitdiff_plain;h=feeb720180e53e2d4e48b1284344c12a3e370867;p=linux.git

PCI: dra7xx: Use generic DesignWare accessors

The dw_pcie_readl_rc() and dw_pcie_writel_rc() interfaces already add in
pp->dbi_base, so use those instead of doing it ourselves in the dra7xx
driver.  No functional change intended.
