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.
Affected configurations
• linux linux kernel (>= 3.8 < 5.15.86)
• linux linux kernel (>= 5.16 < 6.0.16)
• linux linux kernel (>= 6.1 < 6.1.2)
