From f9ad86e42d0303eeb8e0d41bb208153022ebd9d2 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 8 Feb 2017 02:46:01 +0300 Subject: drm/atomic: fix an error code in mode_fixup() Having "ret" be a bool type works for everything except ret = funcs->atomic_check(). The other functions all return zero on error but ->atomic_check() returns negative error codes. We want to propagate the error code but instead we return 1. I found this bug with static analysis and I don't know if it affects run time.
