[WAN]: kfree of NULL pointer is valid
kfree(0) is perfectly valid, checking pointers for NULL before calling kfree() on them is redundant. The patch below cleans away a few such redundant checks (and while I was around some of those bits I couldn't stop myself from making a few tiny whitespace changes as well).
