[PATCH AUTOSEL 6.6 1/6] ASoC: ti: omap-mcbsp: Fix runtime PM underflow warnings

[Sasha Levin]

From: Tony Lindgren <tony@xxxxxxxxxxx>

[ Upstream commit fbb74e56378d8306f214658e3d525a8b3f000c5a ]

We need to check for an active device as otherwise we get warnings
for some mcbsp instances for "Runtime PM usage count underflow!".
