[PATCH v2 2/2] rcuscale: Remove redundant WARN_ON_ONCE() splat

From: Uladzislau Rezki (Sony)
Date: Wed Nov 13 2024 - 06:00:40 EST


There are two places where WARN_ON_ONCE() is called two times
in the error paths. One which is encapsulated into if() condition
and another one, which is unnecessary, is placed in the brackets.

Remove an extra WARN_ON_ONCE() splat which is in brackets.
