[PATCH 3/6] msm: mmc: Remove "pio_irq" resource

From: David Brown
Date: Tue Aug 23 2011 - 13:40:25 EST


From: Sahitya Tummala <stummala@xxxxxxxxxxxxxx>

On some targets, MCI_IRQ_MASK1 is not routed to the MSM in which
case only "cmd_irq" must be used even for PIO. With this change,
all the targets will use only "cmd_irq" for both CMD and PIO.
