If anyone has any objections, please let me know. ------------------ From: Daniel Mack commit decc27b01d584c985c231e73d3b493de6ec07af8 upstream. Coverity spotted an use-after-free condition in snd_soc_remove_platform(). Fix this by moving snd_soc_component_cleanup() after the debug print statement which uses the component's string.
