| Subject: drm/omap: silence unititialized variable warning |
| |
| From: Dan Carpenter <dan.carpenter@oracle.com> |
| |
| [ 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. |
