Subject: [PATCHv2 2/2] PCI/PCIe: Fixups for acpi port setup not being allowed to fail
Date: Fri,  8 Apr 2016 11:35:51 -0600	[thread overview]
Message-ID: <1460136951-28217-3-git-send-email-jonathan.derrick@intel.com> (raw)
In-Reply-To: <1460136951-28217-1-git-send-email-jonathan.derrick@intel.com>

Now that pcie_port_acpi_setup cannot fail, the callers do not need to
check the return values of it and pcie_port_platform_notify.
