From 9319b9da35179e11aa9c15d80062d63b36a0517f Mon Sep 17 00:00:00 2001 From: Jorge Eduardo Candelaria Date: Wed, 12 May 2010 12:18:39 -0500 Subject: [PATCH] ARM: McBSP: Fix request for irq in OMAP4 In OMAP4, there is only one irq line for TX and RX paths. Use the correct irq line to avoid errors at runtime. Also, request irq line only once (instead of requesting for TX and RX).
