Subject: [PATCH 1/2] PCI: Remove reset argument from pci_iov_{add, remove}_virtfn()
Date: Wed, 6 Sep 2017 01:21:22 +0200 [thread overview]
Message-ID: <1504653683-11543-1-git-send-email-jschoenh@amazon.de> (raw)
The reset argument passed to pci_iov_add_virtfn() and
pci_iov_remove_virtfn() is always zero since commit 46cb7b1bd86fc227a
("PCI: Remove unused SR-IOV VF Migration support").
Remove the argument together with the associated code.
Signed-off-by: Jan H. Schönherr <jschoenh@amazon.de>
