Subject: [PATCH] dma-buf: Improve CONFIG_DMABUF_MOVE_NOTIFY help text

Improve the help text for the CONFIG_DMABUF_MOVE_NOTIFY symbol by:
1. Removing duplicated single quotes,
2. Adding a missing subject,
3. Fixing a misspelling of "yet",
4. Wrapping long lines.

Fixes: bb42df4662a44765 ("dma-buf: add dynamic DMA-buf handling v15")

- Don''t pin buffers if the dynamic DMA-buf interface is available on both the

- userspace is able to pin unrestricted amounts of memory through DMA-buf.
