From 5c59065be5a1b347e06d1ad57e017ae2992e606a Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 20 Apr 2016 11:16:31 +0900 Subject: [PATCH] mmc: sdhci-pltfm: call platform_get_irq() before sdhci_alloc_host() Swap the call order of sdhci_alloc_host() and platform_get_irq(). It makes sdhci_alloc_host() the last function that can fail in the sdhci_pltfm_init(). So, we can drop the sdhci_free_host() call from the failure path.
