Subject: ALSA: hda/intel: Use guard() for spinlocks
X-Git-Url: https://www.infradead.org/git/?a=commitdiff_plain;h=cb8fc4337c7e9e8c3431d51c107f32fffd6f2318;p=users%2Fhch%2Fmisc.git

ALSA: hda/intel: Use guard() for spinlocks

Replace the manual spin lock/unlock pairs with guard() for code
simplification.

Only code refactoring, and no behavior change.
