Description
A vulnerability in the Linux kernel's mmc: sdhci-of-aspeed driver was fixed by ensuring that child devices are properly unregistered before releasing parent clock and resources. The issue involved probe failure and removal leaving SDHCI child devices registered after their parent resources were released, which could cause system instability or resource management issues.
