proprietary one to get the necessary data

instance data by struct mbox_client.
Chun-Kuang Hu (4):
soc / drm: mediatek: cmdq: Remove timeout handler in helper function
mailbox / soc / drm: mediatek: Use mailbox rx_callback instead of
For each client driver, its timeout handler need to dump hardware register
or its state machine information, and their way to detect timeout are
also different, so remove timeout handler in helper function and
let client driver implement its own timeout handler.
Signed-off-by: Chun-Kuang Hu
rx_callback is a standard mailbox callback mechanism and could cover the
function of proprietary cmdq_task_cb, so use the standard one instead of
the proprietary one.
