Please run checkpatch --strict on your patches. Never mind, I'll apply the
patch anyway - I see the other entries are the same.

That makes me have a closer look at the code. What is the purpose of the
odd typecast anyway ? Why not just
.driver_data = (void *)aya_neo_2,
and
board = (enum oxp_board)dmi_entry->driver_data;
?

Hello Guenter and thanks for your quick review.

I've run it before on the other patches... did something change in the
checkpatch?
Nevermid, After this one I may submit a patch to fix all styling in one go

I don't know why but the compiler would complain with the casting from
enum to void*.
Found out that explicitly casting the enum literal before casting it
to void* works and
the compiler stopped complaining so I went with it.

As a follow up question, since this driver has become more AYANEO than
OXP since its inception,
wouldn't it be better to change the description?

Really ? I tried with both 32 bit and 64 bit targets, and the above worked
just fine (with W=1). I tried with gcc 10.3 as well as 11.3. What is
your compiler version, what exactly is the warning/error message you
observed, and how exactly did your code look like ?

You are not casting the enum literal, but a pointer to it.

Said something about an invalid cast of an lvalue? I can´t remember exactly
and couldn't reproduce it again. Will change all to your form after
this patch gets
merged if you like, just to keep things atomic.

Yes. I'm taking an enum literal and taking its pointer to cast it to a void*.
A little cumbersome, but maybe it can be avoided by using your proposed
form directly and after making sure it works.

Like this, maybe ?

drivers/hwmon/oxp-sensors.c:63:26: error: lvalue required as unary ‘&’ operand

That would have been something along the line of

.driver_data = (void *)&aok_zoe_a1,

or
driver_data = &aok_zoe_a1,

Please do.
