Subject: [PATCH] ASoC: dmic: Allow GPIO operations to sleep
Git-commit: 5d7e0b1516dfc5901d1e394f17eb55b360e7d3d3
Patch-mainline: v5.8-rc1
References: jsc#SLE-16518

If there is a power GPIO provided we control it from DAPM context so there
is no problem with a sleeping GPIO, use the _cansleep() version of the API
to allow this.
