USB-serial fixes for v4.9-rc2
Here's a fix for a NULL-deref during probe which could be triggered by a
malicious device, and a fix for some missing error handling in cp210x
that also leaked some bits from the stack. Included is also a new device
id for ftdi_sio.

I made a mistake as for naming for this block. The MIO block is not
implemented for these 3 SoCs in the first place. The current naming
will be a trouble if an SoC with both MIO and SD-ctrl blocks appear
in the future.
This driver has just been merged in the previous merge window.
Rename it before the release.

Apparently trying to poke a disabled or non-existent APIC
leads to a box that doesn't even boot. Let's not do that.
No real clue if this is the right fix, but at least my

PowerPC's "cmp" instruction has four operands. Normally people write
"cmpw" or "cmpd" for the second cmp operand 0 or 1. But, frequently
people forget, and write "cmp" with just three operands.
With older binutils this is silently accepted as if this was "cmpw",
while often "cmpd" is wanted. With newer binutils GAS will complain
about this for 64-bit code. For 32-bit code it still silently assumes
"cmpw" is what is meant.
In this instance the code comes directly from ISA v2.07, including the
cmp, but cmpd is correct. Backport to stable so that new toolchains can
build old kernels.

After commit a4675fbc4a7a (cpufreq: intel_pstate: Replace timers with
utilization update callbacks) the cpufreq governor callbacks may not
be invoked on NOHZ_FULL CPUs and, in particular, switching to the
"performance" policy via sysfs may not have any effect on them. That
is a problem, because it usually is desirable to squeeze the last
bit of performance out of those CPUs, so work around it by setting
the maximum P-state (within the limits) in intel_pstate_set_policy()
upfront when the policy is CPUFREQ_POLICY_PERFORMANCE.

These formats store the color information of the image
in a geometrical representation. The colors are mapped into a
cylinder, where the angle is the HUE, the height is the VALUE
and the distance to the center is the SATURATION. This is a very
