Subject: Re: [PATCH 2/5] phy: qualcomm: phy-qcom-qmp: Add PCIe PHY support
for SM8250 SoC
On Wed 16 Sep 08:19 CDT 2020, Manivannan Sadhasivam wrote:
As with the controller patches, it's desirable for $subject to be
succinct and have the prefix match other commits.
So I suggest you go with "phy: qcom-qmp: Add SM8250 PCIe QMP PHYs"
Apart from that I think this change looks good.
Regards,
Bjorn
