Subject: [PATCH] qed: remove an unneed NULL check on list iterator
Date: Sat, 19 Mar 2022 12:36:06 +0800 [thread overview]
Message-ID: <20220319043606.23292-1-xiam0nd.tong@gmail.com> (raw)
The define for_each_pci_dev(d) is:
while ((d = pci_get_device(PCI_ANY_ID, PCI_ANY_ID, d)) != NULL)
Thus, the list iterator 'd' is always non-NULL so it doesn't need to
be checked. So just remove the unnecessary NULL check. Also remove the
unnecessary initializer because the list iterator is always initialized.
