Subject[PATCH 5.14 824/849] remoteproc: imx_rproc: Fix ignoring mapping vdev regions
Date
From: Dong Aisheng <aisheng.dong@nxp.com>

commit afe670e23af91d8a74a8d7049f6e0984bbf6ea11 upstream.

vdev regions are typically named vdev0buffer, vdev0ring0, vdev0ring1 and
etc. Change to strncmp to cover them all.

Fixes: 8f2d8961640f ("remoteproc: imx_rproc: ignore mapping vdev regions")
