Description

In the Linux kernel, the following vulnerability has been resolved: mmc: sdhci-msm: pervent access to suspended controller Generic sdhci code registers LED device and uses host->runtime_suspended flag to protect access to it. The sdhci-msm driver doesn't set this flag, which causes a crash when LED is accessed while controller is runtime suspended. Fix this by setting the flag correctly.
