Subject: [PATCH] accel/kvm: ensure ret always set
Date: Wed, 2 Oct 2019 11:22:12 +0100 [thread overview]
Message-ID: <20191002102212.6100-1-alex.bennee@linaro.org> (raw)
Some of the cross compilers rightly complain there are cases where ret
may not be set. 0 seems to be the reasonable default unless particular
slot explicitly returns -1.
