Subject: [PATCH 4.19 171/219] ASoC: wm2200: add missed operations in remove and probe failure
From: Chuhong Yuan <hslester96@...il.com>
[ Upstream commit 2dab09be49a1e7a4dd13cb47d3a1441a2ef33a87 ]
This driver misses calls to pm_runtime_disable and regulator_bulk_disable
in remove and a call to free_irq in probe failure.
Add the calls to fix it.
