Andy Lutomirski 57d86a0485 PCI/ASPM: Make sysfs link_state_store() consistent with link_state_show() ... If CONFIG_PCIEASPM_DEBUG is set, then PCI devices have a link_state attribute. Reading that attribute shows the state as a bit mask: 1 means L0S upstream, 2 means L0S downstream, and 4 means L1. Oddly, writing to link_state is inconsistent and gets translated, leading to mysterious results in which the value you store isn't comparable the value you load back out. Fix it by making link_state_store() match link_state_show(). [bhelgaas: Check "aspm_disabled" *before* validating input. When "aspm_disabled" is set, this changes the error for invalid input from -EINVAL to -EPERM.] Signed-off-by: Andy Lutomirski <luto@kernel.org> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>		2015-12-03 10:42:59 -06:00
