Subject: remote_driver: Return 'virLockGuard' from 'remoteDriverLock'
X-Git-Tag: v9.0.0-rc1~82
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8d7e3a723da9a885bd0a020a04bd68c9809bf315;p=thirdparty%2Flibvirt.git

remote_driver: Return 'virLockGuard' from 'remoteDriverLock'

The function currently didn't have a return value. Returning the
'virLockGuard' struct allows the callers to use automatic unlocking of
the mutex.
