audit: change decimal constant to macro for invalid uid
SFR reported this 2013-05-15: > After merging the final tree, today's linux-next build (i386 defconfig) > produced this warning: > > kernel/auditfilter.c: In function 'audit_data_to_entry': > kernel/auditfilter.c:426:3: warning: this decimal constant is unsigned only > in ISO C90 [enabled by default] > > Introduced by commit 780a7654cee8 ("audit: Make testing for a valid > loginuid explicit") from Linus' tree. Replace this decimal constant in the code with a macro to make it more readable (add to the unsigned cast to quiet the warning). Cc: Stephen Rothwell <sfr@canb.auug.org.au> Cc: "Eric W. Biederman" <ebiederm@xmission.com> Signed-off-by: Richard Guy Briggs <rgb@redhat.com> Signed-off-by: Eric Paris <eparis@redhat.com>
