Can a wording like the following be nicer for the change description?

  The buffer “__dtb_testcases_begin” will be duplicated to the local
  variable “unittest_data”. Release the corresponding memory
  after a call of the function “of_fdt_unflatten_tree” failed
  in the implementation of the function “unittest_data_add”.
