Subject: [PATCH V2 0/2] Fix two memory leaks in rproc_attach()

In the rproc_attach() function, if rproc_handle_resources() returns
failure, if the rproc->ops->unprepare callback function is not set,
the resources allocated by rproc_prepare_device() cannot be released,
and rproc->clean_table should also be released

patch1 adds rproc->ops->unprepare callback function to imx_rproc
patch2 releases rproc->clean_table

Changes in v2:
    Updated the commit log of these two patches

Xiaolei Wang (2):
  remoteproc: imx_rproc: release carveout under imx_rproc after
    rproc_attach() fails
  remoteproc: core: release rproc->clean_table after rproc_attach()
    fails
