From 47b7360ce563e18c524ce92b55fb4da72b3b3578 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Sat, 8 Sep 2018 12:07:26 +0200 Subject: x86/apic/vector: Make error return value negative activate_managed() returns EINVAL instead of -EINVAL in case of error. While this is unlikely to happen, the positive return value would cause further malfunction at the call site.
