The bottom test is bogus as it is fairly common to do "sizeof *foo" in
addition to "sizeof foo":
: tazenda 139 ; git grep -P 'sizeof\s*[^\(\s]' | wc -l
2085
... but it certainly doesn't change the fact that the kernel coding
style is quite unambiguous. However, I don't think it makes any sense
to patch just for the sake of patching.
I personally like the additional visual clarification (backed by
compiler assertion) that the argument is specifically an object, not a
type ("sizeof type" is invalid), but that's not the prevalent use in
kernel code.
