Prateek Sood 9b6caf4ccb firmware_loader: fix memory leak for paged buffer ... commit 4965b8cd1b upstream. vfree() is being called on paged buffer allocated using alloc_page() and mapped using vmap(). Freeing of pages in vfree() relies on nr_pages of struct vm_struct. vmap() does not update nr_pages. It can lead to memory leaks.
