This patch moves data allocated using kzalloc to managed data allocated
using devm_kzalloc and cleans now unnecessary kfrees in probe and remove
functions. Also, linux/device.h is added to make sure the devm_*()
routine declarations are unambiguously available. Earlier, in the probe
function ctrlpriv was leaked on the failure of ctrl = of_iomap(nprop, 0);
as well as on the failure of ctrlpriv->jrpdev = kzalloc(...); . These
two bugs have been fixed by the patch.
The following Coccinelle semantic patch was used for making the change:
identifier p, probefn, removefn;
@@
struct platform_driver p = {
.probe = probefn,
.remove = removefn,
};
@prb@
identifier platform.probefn, pdev;
expression e, e1, e2;

}

identifier platform.removefn;
