3.14-stable review patch. If anyone has any objections, please let me know. ------------------ From: Sasha Levin <sasha.levin@xxxxxxxxxx> commit 86e4bbc766b9456f583f2fc3c4f6c623b422af88 upstream. Passing a name to request_mem_region() isn't optional and can't just be NULL. Passing NULL causes a NULL ptr deref later in the boot process.
