Claude review: dma-buf: fix htmldocs error for dma_buf_attach_revocable

Patch Review

**Status: Looks good (Reviewed-by worthy)**

The problem: In the kernel-doc comment for `dma_buf_invalidate_mappings()`, the text:

```c
 * accessed:
 *  1) Until dma_resv_wait_timeout() ...
```

is missing a blank comment line between the paragraph ending in `:` and the start of the numbered list. The RST parser doesn't recognize the numbered list without that separator.

The fix adds the required blank `*` line:

```c
 * accessed:
 *
 *  1) Until dma_resv_wait_timeout() ...
```

This is the standard kernel-doc convention — a blank `*` line is needed before a list block for proper RST rendering. I confirmed the current tree at `drivers/dma-buf/dma-buf.c:1355-1356` has exactly this missing blank line.

**Minor nit (non-blocking):** The subject says "for dma_buf_attach_revocable" but the comment being fixed is actually on `dma_buf_invalidate_mappings()`. The Fixes tag correctly points to the commit that introduced the problematic comment, but the subject could be slightly more precise as "fix htmldocs error for dma_buf_invalidate_mappings". This is cosmetic and not worth a respin.

No functional or correctness issues. The patch is trivially correct.
