From ca3c09a74945bfa9db326cee60601f60237e5606 Mon Sep 17 00:00:00 2001 From: Dan Carpenter Date: Wed, 18 Apr 2018 17:29:37 +0300 Subject: [PATCH] drm/omap: silence unititialized variable warning [ Upstream commit 4a9fbfcab19d3f71ad2bf0bcb653c4ee84e69c7f ] Smatch complains that "area_free" could be used without being initialized. This code is several years old and premusably works fine so this can't be a very serious bug. But it's easy enough to silence the warning. If "area_free" is false at the end of the function then we return -ENOMEM.
