From: Adrian Hunter Date: Wed, 29 Jun 2016 13:24:19 +0000 (+0300) Subject: mmc: sdhci-pci: Do not runtime suspend at the end of sdhci_pci_probe() X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=00884b61fb3968da088f7bf26eef9b90233b69df;p=deliverable%2Flinux.git mmc: sdhci-pci: Do not runtime suspend at the end of sdhci_pci_probe() At the successful conclusion of sdhci_pci_probe(), if runtime pm was allowed, the device would be runtime suspended. That wastes a lot of time during initialization. Instead leave the device active until the mmc core scans for a card.
