From 662a74b4b2b7b471417b3778485332a93d07e409 Mon Sep 17 00:00:00 2001 From: Uwe Kleine-König Date: Wed, 20 Oct 2010 17:44:30 +0200 Subject: ARM: mx3: fix build failure concerning MXC_INT_MMC_SDHC2 Commit c074512 (imx-esdhc: update devices registration) renamed MX35_INT_MMC_SDHC2 to MX35_INT_ESDHC2 which broke expansion of the MXC_INT_MMC_SDHC2 macro. As (the only user of MXC_INT_MMC_SDHC2) is only used on mx31 use the MX31 prefixed symbol to define its resources. Moreover to reduce further confusion mxcsdhc_device0 is fixed accordingly and the MXC prefixed symbols are removed.
