[PATCH] resource, kunit: add dependency on SPARSEMEM

[Guenter Roeck]

Building allmodconfig images on systems with SPARSEMEM=n results in
the following message.

WARNING: unmet direct dependencies detected for GET_FREE_REGION
  Depends on [n]: SPARSEMEM [=n]
  Selected by [m]:
  - RESOURCE_KUNIT_TEST [=m] && RUNTIME_TESTING_MENU [=y] && KUNIT [=m]

and the build ultimately fails.

GET_FREE_REGION depends on SPARSEMEM, so any configuration selecting it
also depends on SPARSEMEM. Add the missing dependency.

Effectively that means that RESOURCE_KUNIT_TEST is now restricted to
systems with SPARSEMEM=y, but that can not be helped.
