[PULL 30/30] accel/kvm: ensure ret always set
Posted by Paolo Bonzini 6 years, 4 months ago
From: Alex Bennée <alex.bennee@linaro.org>

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.
