If anyone has any objections, please let me know. ------------------ From: matteo.cotifava [ Upstream commit 3c99c9f0ed60582c1c9852b685d78d5d3a50de63 ] The delayed_work_pending() check before flush_delayed_work() in soc_free_pcm_runtime() is unnecessary and racy. flush_delayed_work() is safe to call unconditionally - it is a no-op when no work is pending. Remove the check. The original check was added by commit 9c9b65203492 ("ASoC: core: only flush inited work during free") but delayed_work_pending() followed by flush_delayed_work() has a time-of-check/time-of-use window where work can become pending between the two calls.
