Hello,
the Subject is wrong, it should use a prefix similar to "serial: imx:".
It's a good idea to check previous patches to the same file to pick a
suitable prefix. (E.g. git log --oneline drivers/tty/serial/imx.c)

you're the third to send this patch since October 20:
https://lore.kernel.org/r/20201026125142.21105-1-zhangqilong3@xxxxxxxxxx
https://lore.kernel.org/r/20201020130709.28096-1-trix@xxxxxxxxxx
My comment for these was:

Zhang Qilong wrote he found the patch opportunity by manual code
inspection, I would have expected that there is a tool that identifies a
break after a return. If you had tool support, please mention the tool
in the commit log (if you really want to keep following the patch's
idea).
Best regards
Uwe
