How do you think about a wording variant like the following?

Change description:
A null pointer check was performed after a call of the
function âdevm_gen_pool_createâ despite of the detail
that failures are indicated by error pointers instead.
Thus adjust a check for the failure predicate
and return the corresponding error code.
