From 021158b4c7bd8d0ec4dc8d09c013288429da7ee2 Mon Sep 17 00:00:00 2001 From: Joe Perches Date: Fri, 13 Feb 2015 14:38:43 -0800 Subject: [PATCH] checkpatch: add types for other OS typedefs bsd and sysv use different typedefs for unsigned types. These are in types.h but not in checkpatch, so add them to checkpatch's ability to know types. This can avoid false positives for code like: void foo(void) { int x; uint y; [...]; } where checkpatch incorrectly emits a warning for "missing a blank line after declarations".
