Subject: ASoC: core: fix use after free in snd_soc_remove_platform()
From: Daniel Mack <daniel@xxxxxxxxxx>
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.
