[PATCH 2/6] Input: adp5589: use devm_kzalloc() to allocate the kpad object

[Alexandru Ardelean <alexandru.ardelean@xxxxxxxxxx>]

This removes the need to manually free the kpad object and cleans up some
exit/error paths.
The error path cleanup should reduce the risk of any memory leaks with this
object.
