Description

In the Linux kernel, the following vulnerability has been resolved:

mfd: macsmc: Initialize mutex

Initialize struct apple_smc's mutex in apple_smc_probe(). Using the
mutex uninitialized surprisingly resulted only in occasional NULL
pointer dereferences in apple_smc_read() calls from the probe()
functions of sub devices.
