Subject: [PATCH] ASoC: wcd_cpe_core: Fix handling of CPE SSR event
It is possible that CPE block on the codec might not be enabled and SSR
event is triggerred, in such cases the CPE is not initialized and the
core handle to CPE is expected to be NULL. Fix the CPE SSR handling to
make sure SSR handling does not proceed if the core handle is NULL.
