0014793459 drm/edid: Have drm_edid.h include hdmi.h
drm_edid.h depends on hdmi.h on account of enum hdmi_picture_aspect,
so let's just include hdmi.h and drop some useless struct declarations.

a6f9dec2a9 ALSA: cs46xx: constify snd_pcm_ops structures
Declare snd_pcm_ops structures as const as they are either stored in the
ops field of a snd_pcm_substream structure or passed as an argument to
the function snd_pcm_set_ops. The function argument and the ops field
are of type const, so snd_pcm_ops structures having this property
can be made const too.

545e3e7da3 Improvements for Exynos PMU driver for v4.11:
Beside basic function of setting proper configuration for low power modes, the
 Exynos PMU (Power Management Unit) driver is also a provider of syscon regmap
 for its registers.  This regmap is essential to many other drivers wanting to
 or needing to implement low power mode.
 
 Exynos pinctrl driver, before getting support for Runtime Power Management,
 needs access to this syscon regmap.  Let's do it in a DT ABI friendly way.

b4cad1bc5f gpio: ws16c48: Utilize devm_ functions in driver probe callback
The devm_ resource manager functions allow memory to be automatically
released when a device is unbound. This patch takes advantage of the
resource manager functions and replaces the gpiochip_add_data call and
request_irq call with the devm_gpiochip_add_data call and
devm_request_irq call respectively. In addition, the ws16c48_remove
function has been removed as no longer necessary due to the use of the
relevant devm_ resource manager functions.

d01f4e8db2 perf ftrace: Introduce new 'ftrace' tool
The 'perf ftrace' command is a simple wrapper of kernel's ftrace

just reads trace_pipe in text and then write it to stdout.

cd4ceb6343 perf util: Save pid-cmdline mapping into tracing header
Current trace info data lacks the saved cmdline mapping which is needed
for pevent to find out the comm of a task.  Add this and bump up the
version number so that perf can determine its presence when reading.

This is mostly corresponding to trace.dat file version 6, but still
lacks 4 byte of number of cpus, and 10 bytes of type string - and I
think we don't need those anyway.

e28ff1a838 tools lib bpf: Add libbpf_get_error()
This function will turn a libbpf pointer into a standard error code (or
0 if the pointer is valid).

This also allows removal of the dependency on linux/err.h in the public
header file, which causes problems in userspace programs built against
libbpf.
