Subject: ASoC: omap-mcpdm: Fix irq resource handling
From: Peter Ujfalusi <peter.ujfalusi@xxxxxx>
commit a8719670687c46ed2e904c0d05fa4cd7e4950cd1 upstream.
Fixes: ddd17531ad908 ("ASoC: omap-mcpdm: Clean up with devm_* function")
Managed irq request will not doing any good in ASoC probe level as it is
not going to free up the irq when the driver is unbound from the sound
card.
