soundwire: amd: fix for handling slave alerts after link is down
[ Upstream commit 86a4371b76976158be875dc654ceee35c574b27b ]
Sometimes, its observed that during system level suspend callback
execution, after link is down, handling pending slave status workqueue
results in mipi register access failures as shown below.
soundwire sdw-master-0-0: trf on Slave 1 failed:-110 read addr 0 count 1
rt722-sdca sdw:0:0:025d:0722:01: SDW_DP0_INT recheck read failed:-110
rt722-sdca sdw:0:0:025d:0722:01: Slave 1 alert handling failed: -110
amd_sdw_manager amd_sdw_manager.0: SDW0 cmd response timeout occurred
amd_sdw_manager amd_sdw_manager.0: command timeout for Slave 1
soundwire sdw-master-0-0: trf on Slave 1 failed:-110 write addr 5c count 1
amd_sdw_manager amd_sdw_manager.0: SDW0 previous cmd status clear failed
amd_sdw_manager amd_sdw_manager.0: command timeout for Slave 1
soundwire sdw-master-0-0: trf on Slave 1 failed:-110 write addr 5d count 1
amd_sdw_manager amd_sdw_manager.0: SDW0 previous cmd status clear failed
amd_sdw_manager amd_sdw_manager.0: command timeout for Slave 1
Cancel the pending slave status workqueue prior to initiating clock stop
sequence during suspend callback execution for both the power modes.
