Summary
In the Linux kernel, the following vulnerability has been resolved: mfd: sm501: Fix potential memory leaks during remove The memory allocated for struct sm501_devdata in sm501_pci_probe() and sm501_plat_probe() is not freed by the corresponding remove functions sm501_pci_remove() and sm501_plat_remove(). Fix that by adding a call to kfree().
