[random:dev 2/9] drivers/char/random.c:682:62: sparse: Using plain integer as NULL pointer

[wfg@linux.intel.com]

Hi Theodore,

Some trivial sparse warnings :)

tree:   git://git.kernel.org/pub/scm/linux/kernel/git/tytso/random.git dev
head:   0ca6c546645d39d68e67b70e5c8f00ad9a955fcb
commit: 4d5ecd27a003dbdecfbaca413803c7d6723cc1d4 [2/9] random: use lockless techniques in the interrupt path

All sparse warnings:
