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.
