EDAC/versalnet: Drop remote processor handle refcount on driver removal

Browse source

mc_probe() acquires a reference to the remote processor with
rproc_get_by_phandle(), but mc_remove() does not release the reference.

rproc_shutdown() only balances the power reference acquired by rproc_boot();
it does not drop the device reference acquired by rproc_get_by_phandle(). As
a result, successful driver removal leaves the remoteproc reference
unbalanced.

Call rproc_put() during removal to release the reference acquired in
mc_probe().
