checkpatch: types: some types may also be identifiers
Some types such as typedefs may overlap real identifiers. Be more targetted about when a type can really exist. Where it cannot let it be an identifier. This prevents false reporting of the minus '-' in unary context in the following: foo[bar->bool - 1]; Signed-off-by: Andy Whitcroft <apw@shadowen.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
