PCI: Simplify pci_find_(ext_)capability() return value checks The return value of the pci_find_(ext_)capability() is either zero or the position of a capability. It is never negative. This patch consolidates the form of check from (pos <= 0) to (!pos). Signed-off-by: Wei Yang <weiyang@linux.vnet.ibm.com> Signed-off-by: Bjorn Helgaas <bhelgaas@google.com>
