Subject: PCI: remove useless pcix_set_mmrbc() dev->bus check
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=809a3bf9f34cb6d0c0383b31b3495fa1ed3508a6;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

PCI: remove useless pcix_set_mmrbc() dev->bus check

For a valid pci_dev, dev->bus != NULL always, so remove this
unnecessary test.
