You have From different to SoB. You need to fix this. It can be done by setting corresponding values in the ~/.gitconfig of your machine where you are making patches on. Quick fix is to run git commit --amend --author="ruihongluo <luoruihong@xxxxxxxxxx>" and resend as a v2. Code wise looks good to me, thank you for fixing this. Perhaps it needs a Fixes tag, as Fixes: 701c5e73b296 ("serial: 8250_dw: add fractional divisor support") added before your SoB line. (Again, use `git commit --amend` to address this.) > Signed-off-by: ruihongluo <luoruihong@xxxxxxxxxx> > --- Also don't forget to add a changelog here for v2 to describe your changes. -- With Best Regards, Andy Shevchenko
