[PATCH 2/2] ASoC: da7219: cancel AAD related work earlier for jack removal

From: Adam Thomson
Date: Mon May 30 2022 - 09:23:01 EST


To avoid the unlikely possibility of register misalignment for
headphones being ungrounded/driven after a jack has been removed,
move the cancel_work_sync() call to the start of the jack removal
handling in the IRQ thread.
