From e46466b8bd5918626250dc0d6cb6c2147a611087 Mon Sep 17 00:00:00 2001 From: Arnaldo Carvalho de Melo Date: Fri, 9 Nov 2012 15:42:26 -0300 Subject: [PATCH] tools lib traceevent: No need to check for < 0 on an unsigned enum MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit gcc on f14 32-bit complains: tools/lib/traceevent/event-parse.c: In function ‘pevent_register_print_function’: tools/lib/traceevent/event-parse.c:5366:3: error: comparison of unsigned expression < 0 is always false This is because: enum pevent_func_arg_type type; this enum doesn't have any negative value, so gcc makes it an 'unsigned int'. Fix it by removing the < 0 test.
