4.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Dan Carpenter <dan.carpenter@xxxxxxxxxx> [ 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.
