Subject: ASoC: codecs: wsa-macro: fix uninitialized stack variables with name prefix
From: Krzysztof Kozlowski <krzysztof.kozlowski@xxxxxxxxxx>
commit 72151ad0cba8a07df90130ff62c979520d71f23b upstream.
Driver compares widget name in wsa_macro_spk_boost_event() widget event
callback, however it does not handle component's name prefix. This
leads to using uninitialized stack variables as registers and register
values. Handle gracefully such case.
