If anyone has any objections, please let me know. ------------------ From: Wolfram Sang [ Upstream commit e088ffa9a00eaaaf90da74763e774ca160969c26 ] hwspin_lock_register_single() always returns 0 despite checking the result from radix_tree_insert(). Propagate the errno to make sanity checks in callers of this function actually meaningful.
