That's still not an explanation.

Why, unless cast away by the code itself, is
const removal a good thing?

It does serve as an indication to a reader what
the code does with the argument.

About the only reason I can think of arguing in
favor of removal is inconsistent application of
const within the module.

It's not so much removal as it is review of the initial driver merge.
I'd contend that const was applied somewhat thoughtlessly originally,
and it didn't really serve a good purpose.

That's one good reason. And not only consistency within the modules,
but consistency within the subsystem (and the kernel at large,
really). There's rarely a case of a const function parameter. And I'm
sure there are numerous function parameters which could potentially be
marked 'const'.

I also don't think that a function parameter is the right place to
mark const like this. Function arguments are always pass-by-value, so
this 'const' tells users (callers) nothing useful. It only provides
useless constraints on what the function can do with its copy of the
parameter.

Again, that's not useless information.

And as you've seen, just making these changes
can be error prone.

For local, pass-by-value function arguments (i.e., constant data, or
constant pointers to data), I respectfully disagree. (For "pointers to
constant data", I completely agree that the 'const' info is useful.)

Thank you for catching our mistake now. But I don't think that is
relevant; just because you caught an error doesn't mean that the change
(primarily for consistency's sake) should be avoided entirely.

Unless you have a more convincing argument, this code will remain as-is.

Brian

Your qualm is not with me in this instance. I don't ever mind holding
my hands up to mistakes I make or standing up for decisions I believe
in, but in this case I'm merely satisfying the wishes of a maintainer
I'm submitting code to.

I am strongly un-opinionated about these particular changes.
