scripts: improve checkstack
Cleanup checkstack script: * Turn on strict checking * Fix resulting error message because the declaration syntax was incorrect. * Remove incorrect and misleading use of prototype - prototype not required for this type of sort function because $a and $b are being used in this contex - if prototype was being used it should be for both arguments * Use closure for sort function Signed-off-by: Stephen Hemminger <shemminger@vyatta.com> Cc: Steven Rostedt <rostedt@goodmis.org> Cc: Arjan van de Ven <arjan@infradead.org> Cc: Cong Wang <amwang@redhat.com> Cc: Michal Marek <mmarek@suse.cz> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Michal Marek <mmarek@suse.cz>
