Hi Syed,

The patch description is just repeating the subject line. Instead, you
should explain why this cleanup improves the module (e.g. makes the code
clearer).

You should also include a Link tag pointing to the previous discussion
about this change.

Link: https://lore.kernel.org/all/20260504063518.515620-1-wbg@kernel.org/

Regardless, I agree with the code changes in this patch so here is my
Ack.
