Re: [PATCH net] net: airoha: Fix DMA direction for NPU mailbox buffer

Hello:

This patch was applied to netdev/net.git (main)
by Paolo Abeni [off-list ref]:

airoha_npu_send_msg() always maps the mailbox buffer with DMA_TO_DEVICE,
but some callers expect the NPU to write response data back into the
same buffer:

- airoha_npu_wlan_msg_get() (NPU_OP_GET): NPU writes response into
  the buffer, then the caller reads it via memcpy()
- airoha_npu_ppe_stats_setup() (NPU_OP_SET): NPU writes back
  npu_stats_addr field in the response
