Sven van Ashbrook 43f588b820 mmc: sdhci-pci-gli: fix LPM negotiation so x86/S0ix SoCs can suspend ... commit 1202d617e3 upstream. To improve the r/w performance of GL9763E, the current driver inhibits LPM negotiation while the device is active. This prevents a large number of SoCs from suspending, notably x86 systems which commonly use S0ix as the suspend mechanism - for example, Intel Alder Lake and Raptor Lake processors. Failure description: 1. Userspace initiates s2idle suspend (e.g. via writing to /sys/power/state) 2. This switches the runtime_pm device state to active, which disables LPM negotiation, then calls the "regular" suspend callback 3. With LPM negotiation disabled, the bus cannot enter low-power state 4. On a large number of SoCs, if the bus not in a low-power state, S0ix cannot be entered, which in turn prevents the SoC from entering suspend. Fix by re-enabling LPM negotiation in the device's suspend callback.
