Subject: Add "destroy" implementation for spinlock.
X-Git-Tag: 12.3.0-rc1~51
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=492c828a54d49188dcd79c41c2729a2a8a71478d;p=thirdparty%2Fasterisk.git

Add "destroy" implementation for spinlock.

The original commit for spinlock was missing "destroy" implementations.
Most of them are no-ops but phtread_spin and pthread_mutex do need their
locks destroyed.
