imx8qxp Malone hardware driver failed to start

A log appears when imx8qxp starts:
[2.255817] [VPU Decoder] warning: init rtx channel failed, ret: -517
[2.262752] [VPU Decoder] failed to request mailbox, ret = -517
[2.274588] [VPU Encoder] warning: init rtx channel failed, ret: -517
[2.281264] [VPU Encoder] fail to request mailbox, ret = -517
Through the tracking code, line 6698 of work-shared/imx8qxpmek/kernel-source/drivers/mxc/vpu_malone/vpu_b0.c appears.

I am using bitbake imx-image-multimedia of imx-yocto-L5.4.47_2.2.0 No changes
