NOMMU: Fix cleanup handling in ramfs_nommu_get_umapped_area()
Fix cleanup handling in ramfs_nommu_get_umapped_area() by only freeing the number of pages that find_get_pages() said it had returned (nr) rather than attempting to free the number of pages we asked for (lpages) - thus avoiding the situation whereby put_page() may be handed NULL pointers if find_get_pages() returned fewer pages that were requested. Also avoid a warning about nr being uninitialised and the need for an if-statement in the cleanup path by using appropriate gotos. Signed-off-by: David Howells <dhowells@redhat.com>
