We accidentally set "psb" which is a no-op instead of "*psb" so it generates a static checker warning. We should probably set it before the first error return so that it's always initialized.

You actually don't need to do either, *psb will be NULL already on entry to the function. But removing the assignment in the error path should be done still.
