Description

In the Linux kernel, the following vulnerability has been resolved:<br /> <br /> ALSA: control: Avoid WARN() for symlink errors<br /> <br /> Using WARN() for showing the error of symlink creations don&amp;#39;t give<br /> more information than telling that something goes wrong, since the<br /> usual code path is a lregister callback from each control element<br /> creation. More badly, the use of WARN() rather confuses fuzzer as if<br /> it were serious issues.<br /> <br /> This patch downgrades the warning messages to use the normal dev_err()<br /> instead of WARN(). For making it clearer, add the function name to<br /> the prefix, too.
