[PATCH 5/5] include/linux/interrupt.h: Require designated initialization of structures

From: Josh Triplett
Date: Thu Jul 31 2014 - 19:48:26 EST


Fix the corresponding tasklet initialization macros to use designated
initializers, which simplifies those initializers using the default
initialization of fields to 0.
