Patch Review

**Verdict: Clean, correct.**

This follows the standard kernel pattern (like `kfree`, `vfree`, etc.) of m=
aking free functions accept NULL:

```c
static void fastrpc_buf_free(struct fastrpc_buf *buf)
{
    if (!buf)
        return;
    // ...
}
```

The two callsite simplifications (`fastrpc_context_free` and `fastrpc_devic=
e_release`) are straightforward and correct. No functional change.

Note that this patch does **not** help with Patch 3's bugs =E2=80=94 the is=
sue there is calling `fastrpc_buf_free` on a non-NULL but improperly initia=
lized `fastrpc_buf`, not passing NULL.
