Subject: [PATCH 1/5] rsi: Device configuration bootup parameters updated

Switch clock info values are changed in the firmware for both 20MHZ
and 40MHZ modes. Hence these values which are configured through boot
parameters request frame are updated. Also three other power save
related parameters are added to boot up parameters.

(Removed over hundred lines of unnecessary quotes, please edit your

Like always, please check the patchwork before sending any emails. The
patch in question is here:

https://patchwork.kernel.org/patch/9427401/

It's in state "Changes Requested" which means that one of patches in the
patchset should have some comments. After looking at the other patches I
see my comment in patch 2:

https://patchwork.kernel.org/patch/9427419/

"Based on Documentation/kernel-documentation.rst this doesn't
look to be valid kernel-doc format. But AFAICS you got the
format correct in patch 3.

Also this function uses negative error codes (as preferred),
it's not just -1 on failure. You should fix that in the comment
(similar problems also elsewhere in this patchset)."
