SubjectRe: [PATCH] drivers: virtio: Use PTR_RET function

WTF is PTR_RET? PTR_RET doesn't return anything. Why is it called
that? It doesn't even make sense.

ZERO_OR_PTR_ERR() maybe.

But what problem are we solving? Insufficient churn in the tree? Code
being too readable? This isn't some hard-to-get right corner case, or a
missed optimization.

Andrew, what am I missing here?

Grumpy,
Rusty.
