Subject: [PATCH v2 2/2] PCI: Rename pci_wakeup_bus() to pci_resume_bus()
Date: Wed, 25 Nov 2020 12:07:33 +0300	[thread overview]
Message-ID: <20201125090733.77782-2-mika.westerberg@linux.intel.com> (raw)
In-Reply-To: <20201125090733.77782-1-mika.westerberg@linux.intel.com>

The previous commit changed the pci_wakeup_bus() to not to signal wakeup
event anymore so rename the function to better match what it does.

Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com>
Reviewed-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

This is new patch as suggested by Bjorn. This one only does the rename. I
added Rafael's tag here too as there are no other changes than the split.
Let me know if it's not OK.
