mm: mmap: fix fput in error path v2
Patch "495c10cc CHROMIUM: dma-buf: restore args..." adds a workaround for a bug in mmap_region. As the comment states ->mmap() callback can change vma->vm_file and so we might call fput() on the wrong file. Revert the workaround and proper fix this in mmap_region. v2: drop the extra if in dma_buf_mmap as well Signed-off-by:Christian König <christian.koenig@amd.com> Reviewed-by:
