Regarding Bjorn's comments: - Use the cover-letter for a multi-patch series. - Correct the subject line, and refine the commit logs. For example, remove the timestamp of the logs. drivers/pci/controller/dwc/pci-imx6.c | 166 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++-------------------------------------- 1 file changed, 105 insertions(+), 61 deletions(-) [PATCH v2 1/5] PCI: imx6: Encapsulate the clock enable into one [PATCH v2 2/5] PCI: imx6: Add the error propagation from host_init [PATCH v2 3/5] PCI: imx6: Fix the regulator dump when link never came [PATCH v2 4/5] PCI: imx6: Fix the clock reference handling unbalance [PATCH v2 5/5] PCI: imx6: Add the compliance tests mode support
