The actual code change itself looks fine, but the above should have gone
into a cover-letter or something like that.

This is not a proper commit message and this is also lacking
your Signed-off-by (which you did correctly include in your
original version:

https://lore.kernel.org/linux-input/20240128214906.60606-1-yaro330@gmail.com/

Please send a v3 with a proper commit-msg + Signed-off-by.

Regards,

Hans
