Both are constants, I think checkpatch is the thing that is wrong here,
don't you agree?

thanks,

Sort of constant-ish...  The sizeof(*value) changes each time the macro
is used.  I feel like checkpatch is right.

That was my take aswell.. PAGE_SIZE is constant for each boot, but
sizeof could change. Happy to be lead by the more experienced here
though.
