[PATCH 4/4] ARM: remove duplicate const qualifier

[Alexandre Belloni]

Hi,

this requires a commit message.

Also, you should think about separating those changes in multiple patches
to ease inclusion in the kernel.

A previous resend patch ;)

http://lists.infradead.org/pipermail/linux-arm-kernel/2016-March/417068.html

And IIRC, the maintainer has merged it.

OK? This seems rather pointless in this case (and even more so for the
typo fix I sent yesterday), but I guess you have some general rule to
enforce. Would this do then?
"The second `const` is unnecessary, and is simply ignored by most compilers."

I'll resend patch #4 as multiple patches. What the way proper to convey
that *multiple* new patches replace *one* old one? Is it enough to just
send those as a reply to this one?

A patch was already submitted for the LPC32xx:

Maybe say you you found it (llvm, sparse, coccinelle?), and why this
is causing a problem for anyone. If it's just unnecessary but not
harmful, I'd probably ignore the patch.

That's fine. Having multiple patches here is slightly better than just
one, but I'd also be fine with just taking the large patch because it
is an identical trivial change in multiple files.

$ grep -rE '(^|\W)const(\s+\w+)+\s+const\s'

I just happened to notice some unnecessary const in our internal code,
so I grep'ed for it in a couple big OSS projects to see how common it
was. Since I found only a few, I decided to remove them, but like I said
it just gets ignored by all the compilers I know, so there's absolutely
no harm in leaving this dead code around.

So, do you want me to split them up? I'd prefer not having to (slightly
less work for me :P), but it doesn't really make much of a difference
either way.

Beware.

I added many of those exactly because gcc did not ignore them when 
compiling with LTO where the lack of a const qualifier to qualify the 
actual array content, and not only the reference to that content, 
generated build errors due to section mismatches from the __initconst 
annotation.

So this is a NAK from me unless you may confirm that LTO builds are 
unaffected by your changes.

I believe the first `const` does that, without the need for a second.

I can't confirm it (haven't tried), and don't care enough to do it :]
I guess I'm just dropping the patch then. Like I said, it can't hurt to
leave them in.

Actually it may hurt (a little bit) - it makes the code less readable.

I just tested LTO with your patch applied and everything appears to be 
fine.  The extra const are indeed redundant here. So you have an ACK 
from me.
