mmc: sdhci-pci: Do not runtime suspend at the end of sdhci_pci_probe() (00884b61) · Commits · 戴 / test

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. Signed-off-by:
