Subject[PATCH] sparse cleanups: NULL pointers, C99 struct init.
From: Randy Dunlap <rdunlap@xenotime.net>

Convert most of the remaining "Using plain integer as NULL pointer"
sparse warnings to use NULL.
(Not duplicating patches that are already in -mm, -bird, or -kj.)

Convert isdn driver struct initializer to use C99 syntax.
