Subject: tmio_mmc: keep card-detect interrupts enabled
From: Guennadi Liakhovetski <g.liakhovetski@xxxxxx>
On SuperH platforms the SDHI controller does not produce any command IRQs after
a completed IO. This leads to card-detect interrupts staying disabled. Do not
disable card-detect interrupts on DATA IRQs.
