I check other platforms, it is 'static const struct pci_epc_features', I can get the correct

You should fix your email client set-up to avoid sticking an [EXT]

See above, this "Caution" stuff should disappear.
Also, quoting the email header is useless, please configure your email
client to remove it.

Do you see any commit with a $SUBJECT ending with a period ?
There is not. So remove it from yours too.

Now, with the output you get justify all the people you send this email
to.
So, again, trim the CC list and it is the last time I tell you.
Before sending patches on mailing lists use git --dry-run to check
the emails you are sending.
Thanks,
Lorenzo

Do you mean that I use scripts/get_maintainer.pl -f drivers/pci/controller/
dwc/pci-layerscape-ep.c to get the mail list who I need to send? I use the
command of ' scripts/get_maintainer.pl *.patch' to get the mail list before.
If yes, I will use the command that you provided. Thanks a lot.
