From 4a92fe80becbbee650cfad8457ad0e5cd97ed974 Mon Sep 17 00:00:00 2001 From: Sahitya Tummala Date: Mon, 2 May 2011 18:07:43 +0530 Subject: [PATCH] msm: mmc: Remove "pio_irq" resource 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.
