[PATCH] pci: ptm: remove error message at boot

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Since commit 39850ed51062 ("PCI/PTM: Save/restore Precision
Time Measurement Capability for suspend/resume") devices
which have PTM capability but don't enable it see this
message on calls to pci_save_state():

  "no suspend buffer for PTM"

Drop the message, it's perfectly fine not to use a capability.

Fixes: 39850ed51062 ("PCI/PTM: Save/restore Precision Time Measurement Capability for suspend/resume")
