In subject and commit log: PCI: cadence: Add missing return in cdns_plat_pcie_probe() When cdns_plat_pcie_probe() succeeds, return success instead of falling into the error handling code. We should have a Fixes: tag here to show where this bug was introduced. Look at previous git history to see the format. Maybe also a stable tag so this will get backported to stable kernels. Interesting that nobody noticed such an obvious bug until now. > Signed-off-by: Li Chen <lchen@ambarella.com> > Signed-off-by: Xuliang Zhang <xlzhanga@ambarella.com> Since the patch was sent by Li, that signoff should be last, per https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/Documentation/process/submitting-patches.rst?id=v5.14#n365 Reviewed-by: Bjorn Helgaas <bhelgaas@google.com> Thanks for the patch! > --- > drivers/pci/controller/cadence/pcie-cadence-plat.c | 2 ++ > 1 file changed, 2 insertions(+) > > diff --git a/drivers/pci/controller/cadence/pcie-cadence-plat.c b/drivers/pci/controller/cadence/pcie-cadence-plat.c > index 5fee0f89ab59..a224afadbcc0 100644 > --- a/drivers/pci/controller/cadence/pcie-cadence-plat.c > +++ b/drivers/pci/controller/cadence/pcie-cadence-plat.c > @@ -127,6 +127,8 @@ static int cdns_plat_pcie_probe(struct platform_device *pdev) > goto err_init; > } > > + return 0; > + > err_init: > err_get_sync: > pm_runtime_put_sync(dev); > -- > 2.33.0 > > ********************************************************************** > This email and attachments contain Ambarella Proprietary and/or Confidential Information and is intended solely for the use of the individual(s) to whom it is addressed.
