Subject: [PATCH v2 00/17] firewire: core/ohci: use guard macro for any type of lock primitives

Hi,

This patchset is a revised version of the previous one.

https://lore.kernel.org/lkml/20240804130225.243496-1-o-takashi@sakamocchi.jp/

The guard macro was firstly introduced in v6.5 kernel, and already
available for spin_lock, mutex, RCU, and R/W semaphore. It is useful to
ensure releasing lock in block.

This patchset includes changes to replace lock/release codes with the guard
macro.

* Changes in v2:
  * use scoped_guard() instead of guard() just after label so that
    statements are expanded there instead of declarations.
