5.4-stable review patch. If anyone has any objections, please let me know. ------------------ From: Kamil Duljas <kamil.duljas@xxxxxxxxx> [ Upstream commit f8ba14b780273fd290ddf7ee0d7d7decb44cc365 ] skl_platform_register() uses krealloc. When krealloc is fail, then previous memory is not freed. The leak is also when soc component registration failed.
