EDAC/{sb,i7core}_edac: Do not use a plain integer for a NULL pointer
Sparse warns about the use of the integer constant 0 as a NULL pointer with the -Wnon-pointer-null switch. Even though the C standard requires that 0 == NULL and type conversion rules turn an integer constant 0 into a NULL pointer when cast to a void * type, Linus notes that this is a very poor situation from a type safety angle and a pointer should be initialized with a pointer type - not an integer constant. See https://www.spinics.net/lists/linux-sparse/msg10066.html for more info.
