Please fix the commit message. I use b4 to apply patches.
Documentation/process/submitting-patches.rst
or https://docs.kernel.org/process/submitting-patches.html
https://docs.kernel.org/process/email-clients.html

Also you can see how patches are reviewed, the style used

(hint: don't add (v2) as postfix in $subject)

PS: if you are not comfortable with upstream patch flow, I suggest
online training/in-person training from various sources such as bootlin
