From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>
3.12-stable review patch. If anyone has any objections, please let me know.
===============
commit 10640d34552ccd8fabe7b15b0c4e3a102247952d upstream.
If you pass an invalid string here then you probably deserve the memory
corruption, but it annoys static analysis tools so lets fix it.
