I would add a comment here explaining why this condition is checked and
what it means. Maybe something like the following ?

+ /*
+ * Check if the kunit test suite start address is a virtual
+ * address or a direct mapping address. This is used as an
+ * indication of whether the kunit_filter_suites() was used
+ * to filter the kunit test suite or not.
+ *
+ * If is not a virtual address, then this means that the
+ * kunit_module_init() function was not called and the kunit
+ * suite was not filtered. Let's just bail out in that case.
+ */
+ if (!suite_set.start || !virt_addr_valid(suite_set.start))
+ return;

The patch makes sense to me though and agree that is a better approach.
