Subject: mmc: sdhci-pci-gli: Fix GL9763E runtime PM when the system resumes from suspend
From: Ben Chuang <benchuanggli@xxxxxxxxx>
commit 291e7d52d19f114cad6cbf802f3f19ef12a011f8 upstream.
When the system resumes from suspend (S3 or S4), the power mode is
MMC_POWER_OFF. In this status, gl9763e_runtime_resume() should not enable
PLL. Add a condition to this function to enable PLL only when the power
mode is MMC_POWER_ON.
