Hi Victor, One thing, get in the habit of running checkpatch.pl before submitting patches. checkpatch.pl says. "From:/Signed-off-by: email address mismatch: 'From: Victor Shih <victorshihgli@gmail.com>' != 'Signed-off-by: Victor Shih <victor.shih@genesyslogic.com.tw>'" It reminds you that maybe the first line of the email body needs a line "Form: Victor Shih <victor.shih@genesyslogic.com.tw>'". man git-format-patch and see --form option Best regards, Ben On Fri, May 12, 2023 at 6:47 PM Victor Shih <victorshihgli@gmail.com> wrote: > > Add support for the GL9767 chipset.
