checkpatch: prefer static const declarations
There are about 100,000 uses of 'static const <type>' but about 400 uses
of 'static <type> const' in the kernel where type is not a pointer.
The kernel almost always uses "static const" over "const static" as there
is a compiler warning for that declaration style.
But there is no compiler warning for "static <type> const".
So add a checkpatch warning for the atypical declaration uses of.
const static <type> <foo>
and
static <type> const <foo>
For example:
$ ./scripts/checkpatch.pl -f --emacs --quiet --nosummary -types=static_const arch/arm/crypto/aes-ce-glue.c
arch/arm/crypto/aes-ce-glue.c:75: WARNING: Move const after static - use 'static const u8'
