4.14-stable review patch. If anyone has any objections, please let me know.
------------------
From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx>
[ Upstream commit de6f83f85be94e0b7d0d324c29ccc9d78a6bb4e7 ]
If 'of_device_get_match_data()' fails, we must undo the previous
'rproc_alloc()' call.
Fixes: a0ff4aa6f010 ("remoteproc: imx_rproc: add a NXP/Freescale imx_rproc driver")
