[PATCH 02/30] qemu: Don't take double pointer in qemuDomainSecretInfoFree

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Using a doulble pointer prevents the function from being used as the
automatic cleanup function for the given type.

Remove the double pointer use by replacing the calls with
g_clear_pointer which ensures that the pointer is cleared.
