New subject: [libvirt] [PATCH v2 3/4] utils: Remove ATTRIBUTE_NONNULL(1) from virCommandSetSendBuffer
Remove the ATTRIBUTE_NONNULL(1) from virCommandSetSendBuffer()
prototype since we are checking for '!cmd' and move the initialization
if 'i' after the test for '!cmd'.

New subject: [libvirt] [PATCH v2 4/4] conf: Remove ATTRIBUTE_NONNULL(2) from virDomainCheckDeviceChanges()
Since we are checking the 2nd parameter in the function for NULL,
we need to remove ATTRIBUTE_NONNULL(2) from the prototype.
