From 39a594dc0b4ac949edf221db33c7061c45e2c90b Mon Sep 17 00:00:00 2001 From: Richard Fitzgerald Date: Tue, 11 Apr 2023 16:25:23 +0100 Subject: ASoC: cs35l56: Remove quick-cancelling of dsp_work() Delete the 'removing' flag and don't kick init_completion to make a quick cancel of dsp_work(). Just let it timeout on the wait for the completion. Simplify the code to standard cancelling or flushing of the work. This avoids introducing corner cases from a layer of custom signalling. It also avoids potential race conditions when system-suspend handling is added. Unless the hardware is broken, the dsp_work() will already have started and passed the completion before the driver would want to cancel it.
