Subject[PATCH] of: unittest: fix memory leak in unittest_data_add
Date
In unittest_data_add, a copy buffer is created via kmemdup. This buffer
is leaked if of_fdt_unflatten_tree fails. The release for the
unittest_data buffer is added.

Fixes: b951f9dc7f25 ("Enabling OF selftest to run without machine's devicetree")
