Pull locking updates from Ingo Molnar: "Locking primitives: - Mark devm_mutex_init() as __must_check and fix drivers that didn't check the return code (Thomas Weißschuh) - Reorganize <linux/local_lock.h> to better expose the internal APIs to local variables (Sebastian Andrzej Siewior) - Remove OWNER_SPINNABLE in rwsem (Jinliang Zheng) - Remove redundant #ifdefs in the mutex code (Ran Xiaokai) Lockdep: - Avoid returning struct in lock_stats() (Arnd Bergmann) - Change `static const` into enum for LOCKF_*_IRQ_* (Arnd Bergmann) - Temporarily use synchronize_rcu_expedited() in lockdep_unregister_key() to speed things up. (Breno Leitao) Rust runtime: - Add #[must_use] to Lock::try_lock() (Jason Devers)" * tag 'locking-core-2025-07-29' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip: lockdep: Speed up lockdep_unregister_key() with expedited RCU synchronization locking/mutex: Remove redundant #ifdefs locking/lockdep: Change 'static const' variables to enum values locking/lockdep: Avoid struct return in lock_stats() locking/rwsem: Use OWNER_NONSPINNABLE directly instead of OWNER_SPINNABLE rust: sync: Add #[must_use] to Lock::try_lock() locking/mutex: Mark devm_mutex_init() as __must_check leds: lp8860: Check return value of devm_mutex_init() spi: spi-nxp-fspi: Check return value of devm_mutex_init() local_lock: Move this_cpu_ptr() notation from internal to main header
