Description
A vulnerability in the Linux kernel's sdhci-sprd driver involves improper handling of runtime power management (PM) during device removal. The driver enables runtime PM on probe but does not correctly disable it on removal, potentially leading to clock management issues if the device is runtime suspended. The issue was identified through manual code inspection and has been fixed in specific commits.
