static checker complains, that the block already breaks if IS_ERR(np)
and thus the extra !IS_ERR(np) check in the while condition is
superfluous. Avoid the extra check by using while(true) instead. This
should not change the runtime behavior at all and I expect the binary
to be more or less the same for an optimizing compiler.
