I thought that in your previous review you meant to say that we should avoid 2 instances of the same comment (in this patchset I only have this instance as I have removed the same comment from patch 2/2...) > > > pcie_capability_read_word(dev, PCI_EXP_FLAGS, ®16); > > entry = (reg16 & PCI_EXP_FLAGS_IRQ) >> 9; > > @@ -100,7 +107,10 @@ static int pcie_port_enable_msix(struct pci_dev > *dev, int *irqs, int mask) > > * MSI/MSI-X vectors assigned to the port is going to be > used > > * for AER, where "For MSI-X, the value in this register > > * indicates which MSI-X Table entry is used to generate > the > > - * interrupt message." > > + * interrupt message." and "For MSI, the value > > + * in this field indicates the offset between the base > Message > > + * Data and the interrupt message that is generated." > > + * > > */ > > And while this is getting a little too deep into nitpicking: we > usually > don't add empty lines to the end of comments. Ok I can remove the extra line and send out patch v4... Many thanks Gab
