From 5c3c6126b62d29f539a8712c65c58afc9c9d2c91 Mon Sep 17 00:00:00 2001 From: Adrian Hunter Date: Tue, 9 Jan 2018 09:52:18 +0200 Subject: mmc: sdhci-pci: Stop calling sdhci_enable_irq_wakeups() sdhci_enable_irq_wakeups() is already called by sdhci_suspend_host() so sdhci-pci should not need to call it. However sdhci_suspend_host() only calls it if wakeups are enabled, and sdhci-pci does not enable them until after calling sdhci_suspend_host(). So move the calls to sdhci_pci_init_wakeup() before calling sdhci_suspend_host(), and stop calling sdhci_enable_irq_wakeups(). That results in some simplification because sdhci_pci_suspend_host() and __sdhci_pci_suspend_host() no longer need to be separate functions.
