Srinivas Kandagatla f9a470db27 misc: fastrpc: Add missing lock before accessing find_vma() ... fastrpc driver is using find_vma() without any protection, as a result we see below warning due to recent patch 5b78ed24e8 ("mm/pagemap: add mmap_assert_locked() annotations to find_vma*()") which added mmap_assert_locked() in find_vma() function. This bug went un-noticed in previous versions. Fix this issue by adding required protection while calling find_vma().
