From d4377f43afa93d81f4e789a58a2c820083b4c85d Mon Sep 17 00:00:00 2001 From: Chun-Kuang Hu Date: Thu, 1 Jul 2021 21:20:53 +0800 Subject: [PATCH] drm/mediatek: Use mailbox rx_callback instead of cmdq_task_cb 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.
