[PATCH 1/1] drivers/base/dma-buf.c: replace dma_buf_uninit_debugfs by debugfs_remove_recursive

[Fabian Frederick <fabf@skynet.be>]

null test before debugfs_remove_recursive is not needed so one line function
dma_buf_uninit_debugfs can be removed.

This patch calls debugfs_remove_recursive under CONFIG_DEBUG_FS
