Fix the following checker warning:
net/rxrpc/call_object.c:279 rxrpc_new_client_call()
warn: passing zero to 'ERR_PTR'
where a value that's always zero is passed to ERR_PTR() so that it can be
passed to a tracepoint in an auxiliary pointer field.
Just pass NULL instead to the tracepoint.

This set of changes contains support for PWM signal capture in the STi
driver as well as support for the PWM controller found on Meson SoCs.
There's also support added for the MediaTek MT2701 and SunXi H3 to the
existing drivers.
Other than that there's a fair set of miscellaneous cleanups and fixes
across the board.

Pull thermal managament updates from Zhang Rui:
- Enhance thermal "userspace" governor to export the reason when a
thermal event is triggered and delivered to user space. From Srinivas
Pandruvada
- Introduce a single TSENS thermal driver for the different versions of
the TSENS IP that exist, on different qcom msm/apq SoCs'. Support for
msm8916, msm8960, msm8974 and msm8996 families is also added. From
Rajendra Nayak
- Introduce hardware-tracked trip points support to the device tree
thermal sensor framework. The framework supports an arbitrary number
of trip points. Whenever the current temperature is changed, the trip
points immediately below and above the current temperature are found,
driver callback is invoked to program the hardware to get notified
when either of the two trip points are triggered. Hardware-tracked
trip points support for rockchip thermal driver is also added at the
same time. From Sascha Hauer, Caesar Wang
- Introduce a new thermal driver, which enables TMU (Thermal Monitor
Unit) on QorIQ platform. From Jia Hongtao
- Introduce a new thermal driver for Maxim MAX77620. From Laxman

This affectively reverts commit 377ccbb483 ("Makefile: Mute warning
for __builtin_return_address(>0) for tracing only") because it turns out
that it really isn't tracing only - it's all over the tree.
We already also had the warning disabled separately for mm/usercopy.c
(which this commit also removes), and it turns out that we will also
want to disable it for get_lock_parent_ip(), that is used for at least
TRACE_IRQFLAGS. Which (when enabled) ends up being all over the tree.
Steven Rostedt had a patch that tried to limit it to just the config
options that actually triggered this, but quite frankly, the extra
complexity and abstraction just isn't worth it. We have never actually
had a case where the warning is actually useful, so let's just disable
it globally and not worry about it.

While looking at a patch that introduced a compile-time warning
"‘pmc_core_dev_state_get’ defined but not used" (I sent a patch
for debugfs to fix it), I noticed that the same patch caused
it in intel_pmc_core also introduced a bogus run-time warning:
"PMC Core: debugfs register failed".
The problem is the IS_ERR_OR_NULL() check that as usual gets
things wrong: when CONFIG_DEBUGFS_FS is disabled,
debugfs_create_dir() fails with an error code, and we don't
need to warn about it, unlike the case in which it returns
NULL.
This reverts the driver to the previous state of not warning
about CONFIG_DEBUGFS_FS being disabled. I chose not to
restore the driver to making a runtime error in debugfs
fatal in pmc_core_probe().
