Bartosz Golaszewski a19ce320c3 power: sequencing: fix an invalid pointer dereference in error path 
We may end up calling pwrseq_target_free() on a partially initialized
target object whose unit is either NULL or an ERR_PTR(). Avoid
dereferencing invalid memory by adding an appropriate check to
pwrseq_target_free().
