## Description

In the Linux kernel, the following vulnerability has been resolved:  mmc: rtsx_pci: fix return value check of mmc_add_host()  mmc_add_host() may return error, if we ignore its return value, the memory that allocated in mmc_alloc_host() will be leaked and it will lead a kernel crash because of deleting not added device in the remove path.  So fix this by checking the return value and calling mmc_free_host() in the error path, beside, runtime PM also needs be disabled.
