the if statement in lb_modinit is unnecessary so we can totally
remove the variable ret and just return the return value from
the call to usb_function_register.

Problems with the signal integrity of the high speed USB data lines or
noise on reference ground lines can cause the i.MX6 USB controller to
violate USB specs and exhibit unexpected behavior.
It was observed that USBi_UI interrupts were triggered first and when
isr_setup_status_phase was called, ci->status was NULL, which lead to a
NULL pointer dereference kernel panic.
This patch fixes the kernel panic, emits a warning once and returns
-EPIPE to halt the device and let the host get stalled.
It also adds a comment to point people, who are experiencing this issue,
to their USB hardware design.

Add myself to the SAMSUNG SOC CLOCK DRIVERS entry, I'm going to review
and test related patches as supporter. I can access all the datasheet
of Exynos SoC series and can do tests on Exynos based boards. I have
implemented the exynos4415/5433 clock drivers and co-authored the
exynos3250 clock driver. While at it, add missing paths of the exynos
clock driver files.

In case of inter address family tunneling (IPv6 over vti4 or IPv4 over
vti6), the inbound policy checks in vti_rcv_cb() and vti6_rcv_cb() are
using the wrong address family. As a result, all inbound inter address
family traffic is dropped.
Use the xfrm_ip2inner_mode() helper, as done in xfrm_input() (i.e., also
increment LINUX_MIB_XFRMINSTATEMODEERROR in case of error), to select the
inner_mode that contains the right address family for the inbound policy
checks.

When we fail to attach the security context in xfrm_state_construct()
we'll return 0 as error value which, in turn, will wrongly claim success
to userland when, in fact, we won't be adding / updating the XFRM state.
This is a regression introduced by commit fd21150a0fe1 ("[XFRM] netlink:
Inline attach_encap_tmpl(), attach_sec_ctx(), and attach_one_addr()").
Fix it by propagating the error returned by security_xfrm_state_alloc()
in this case.

git://git.kernel.org/pub/scm/linux/kernel/git/acme/linux into perf/core
Pull perf/core improvements and fixes from Arnaldo Carvalho de Melo:
User visible changes:
- Add branch stack / basic block info to 'perf annotate --stdio', where for
each branch, we add an asm comment after the instruction with information on
how often it was taken and predicted. See example with color output at:
http://vger.kernel.org/~acme/perf/annotate_basic_blocks.png
(Peter Zijlstra)
- Only open an evsel in CPUs in its cpu map, fixing some use cases in
systems with multiple PMUs with different CPU maps (Mark Rutland)
- Fix handling of huge TLB maps, recognizing it as anonymous (Wang Nan)
Infrastructure changes:
- Remove the symbol filtering code, i.e. the callbacks passed to all functions
that could end up loading a DSO symtab, simplifying the code, eventually
allowing what we should have had since day one: removing the 'map' parameter
from dso__load() functions (Arnaldo Carvalho de Melo)
Arch specific build fixes:
- Fix detached tarball build on powerpc, where we were still accessing a
file outside tools/ (Ravi Bangoria)

Simplify code and reduce code size by using the new hwmon
registration API.
Other changes:
- Convert to use regmap, and drop local caching. This avoids reading
registers unnecessarily, and uses regmap for caching of non-volatile
registers.
- Add support for temp2_max, temp2_max_alarm, temp2_max_hyst, and
temp2_offset.
- Order include files alphabetically
- Drop FSF address
- Check errors from register read and write functions and report
to userspace.
- Accept negative hysteresis values. While unlikely, a maximum limit
_can_ be set to a value smaller than 31 degrees C, which makes negative
hysteresis values possible.

The system crashes during probing xgene-hwmon driver when temperature
alarm interrupt occurs before.
It's because
- xgene_hwmon_probe() requests mailbox channel which also enables
the mailbox interrupt.
- As temperature alarm interrupt is pending, ISR runs and crashes when
accesses into invalid resourse as unmapped PCC shared memory.
This patch fixes this issue by saving this alarm message and scheduling a
bottom handler after xgene_hwmon_probe() finish.

iio_channel_get_all returns -ENODEV when it cannot find either phandles and
properties in the Device Tree or channels whose consumer_dev_name matches
iio_hwmon in iio_map_list. The iio_map_list is filled in by iio drivers
which might be probed after iio_hwmon.
It is better to defer the probe of iio_hwmon if such error is returned by
iio_channel_get_all in order to let a chance to iio drivers to expose
channels in iio_map_list.

Since commit 698a7c24a544 ("hwmon: (nct6775) Support two SuperIO chips
in the same system"), the driver supports two Super-IO chips. This has
the undesirable side effect that force_id always detects a second chip
at address 0xfff8, even if no chip exists at that address.
nct6775: Found NCT6793D or compatible chip at 0x4e:0xfff8
If no chip at all is found at a given SIO address, it does not make sense
to instantiate it. Limit force_id to only work if some chip is found,
that is if the chip ID returns a value other than 0xffff.

Up to now, each hwmon driver has to implement its own sysfs attributes.
This requires a lot of template code, and distracts from the driver's core
function to read and write chip registers.
To be able to reduce driver complexity, move sensor attribute handling
and thermal zone registration into hwmon core. By using the new API,
driver code and data size is typically reduced by 20-70%, depending
on driver complexity and the number of sysfs attributes supported.
With this patch, the new API only supports thermal sensors. Support for
other sensor types will be added with subsequent patches.
