Subject: [PATCH 2/2] ASoC: da7219: cancel AAD related work earlier for jack removal
Date: Mon, 30 May 2022 13:22:23 +0000	[thread overview]
Message-ID: <b3f9a679f1e27a9359dcecb496953c4af30acbaa.1653916368.git.DLG-Adam.Thomson.Opensource@dm.renesas.com> (raw)
In-Reply-To: <cover.1653916368.git.DLG-Adam.Thomson.Opensource@dm.renesas.com>

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.
