In some contexts, the subject line is not visible at the same time. It's fine to repeat the subject in the commit log. > Signed-off-by: Pali Rohár > Reviewed-by: Marek Behún > Fixes: 23a5fba4d941 ("PCI: Introduce PCI bridge emulated config space common logic") > Cc: stable@vger.kernel.org # e0d9d30b7354 ("PCI: pci-bridge-emul: Fix big-endian support") I'm not sure how people would deal with *two* SHA1s. This patch adds functionality, so it's not really fixing a bug in 23a5fba4d941. I see that e0d9d30b7354 came along later and did "s/u16 rsvd/__le16 rsvd/". But it seems like a lot to expect for distros and stable kernel maintainers to interpret this. Personally I think I would omit both Fixes: and the stable tag since these two patches (05 and 06) are just adding functionality. > --- > drivers/pci/pci-bridge-emul.h | 2 +- > 1 file changed, 1 insertion(+), 1 deletion(-) > > diff --git a/drivers/pci/pci-bridge-emul.h b/drivers/pci/pci-bridge-emul.h > index b31883022a8e..49bbd37ee318 100644 > --- a/drivers/pci/pci-bridge-emul.h > +++ b/drivers/pci/pci-bridge-emul.h > @@ -54,7 +54,7 @@ struct pci_bridge_emul_pcie_conf { > __le16 slotctl; > __le16 slotsta; > __le16 rootctl; > - __le16 rsvd; > + __le16 rootcap; > __le32 rootsta; > __le32 devcap2; > __le16 devctl2; > -- > 2.20.1 >
