> Subject: [Intel-wired-lan] [PATCH net] idpf: fix mismatched free
> function for dma_alloc_coherent
>
> The mailbox receive path allocates coherent DMA memory with
> dma_alloc_coherent(), but frees it with dmam_free_coherent().
> This is incorrect since dmam_free_coherent() is only valid for buffers
> allocated with dmam_alloc_coherent().
>
> Fix the mismatch by using dma_free_coherent() instead of
> dmam_free_coherent

> Fixes: e54232da1238 ("idpf: refactor idpf_recv_mb_msg")
