[PATCH 5/9] x86/pci: Rename acpi_mcfg_check_entry() to acpi_mcfg_valid_entry()

[Bjorn Helgaas]

From: Bjorn Helgaas <bhelgaas@xxxxxxxxxx>

"acpi_mcfg_check_entry()" doesn't give a hint about what the return value
means.  Rename it to "acpi_mcfg_valid_entry()", convert the return value to
bool, and update the return values and callers to match so testing
"if (acpi_mcfg_valid_entry())" makes sense.
