[PATCH] livepatch: match return value to function signature

From: Nicholas Mc Guire
Date: Mon May 11 2015 - 02:00:47 EST

klp_initialized() should return bool but is actually returning
struct kobject * - convert it to a boolean explicitly.

Signed-off-by: Nicholas Mc Guire <hofrat@xxxxxxxxx>

static code checking was not happy with
./kernel/livepatch/core.c:131 WARNING: return of wrong type
bool != struct kobject *

This adds !! to explicitly convert to boolean type.

Patch was compile tested with x86_64_defconfig

patch is against 4.1-rc2 (localversion-next is -next-20150508)
