Because clk_prepare_enable and clk_disable_unprepare should
check input clock parameter is NULL or not internally, then
we don't need to check them before calling the function.

To turn the headphone output switch off during jack type detection, it
could avoid the pop noise when jack type switches to OMTP type.

We have a Dell AIO, there is neither internal speaker nor internal
mic, only a multi-function audio jack on it.

Users reported that after freshly installing the OS and plug
a headset to the audio jack, the headset can't output sound. I
reproduced this bug, at that moment, the Input Source is as below:
Simple mixer control 'Input Source',0
  Capabilities: cenum
  Items: 'Headphone Mic' 'Headset Mic'
  Item0: 'Headphone Mic'

That is because the patch_realtek will set this audio jack as mic_in
mode if Input Source's value is hp_mic.

If it is not fresh installing, this issue will not happen since the
systemd will run alsactl restore -f /var/lib/alsa/asound.state, this
will set the 'Input Source' according to history value.

If there is internal speaker or internal mic, this issue will not
happen since there is valid sink/source in the pulseaudio, the PA will
set the 'Input Source' according to active_port.

To fix this issue, change the parser function to let the hs_mic be
stored ahead of hp_mic.

Commit f0bd62b ("ALSA: usb-audio: Improve frames size computation")
introduced a regression for devices which have playback endpoints with
bInterval > 1. Fix this by taking ep->datainterval into account.

Note that frame and fps are actually mean packet and packets per second
in the code introduces by the mentioned commit. This will be fixed in a
follow-up patch.

ASoC: Fixes for v5.8

A few small driver specific fixes, nothing particularly dramatic.
The stack object “info” in snd_opl3_ioctl() has a leaking problem.
It has 2 padding bytes which are not initialized and leaked via
“copy_to_user”.

When HDMI PCM devices are opened in a specific order, with at least one
HDMI/DP receiver connected, ALSA PCM open fails to -EBUSY on the
connected monitor, on recent Intel platforms (ICL/JSL and newer). While
this is not a typical sequence, at least Pulseaudio does this every time
when it is started, to discover the available PCMs.

The rootcause is an invalid assumption in hdmi_add_pin(), where the
total number of converters is assumed to be known at the time the
function is called. On older Intel platforms this held true, but after
ICL/JSL, the order how pins and converters are in the subnode list as
returned by snd_hda_get_sub_nodes(), was changed. As a result,
information for some converters was not stored to per_pin->mux_nids.
And this means some pins cannot be connected to all converters, and
application instead gets -EBUSY instead at open.

The assumption that converters are always before pins in the subnode
list, is not really a valid one. Fix the problem in hdmi_parse_codec()
by introducing separate loops for discovering converters and pins.

The HDMI codec driver has two debug traces printed from different
functions but with identical message content:

"HDMI: hinfo 000000006a6b84d9 not registered"

Fix this duplication and also add a bit more context in addition to raw
object pointer, to help analysis of kernel logs.

1)
In snd_hda_pick_fixup(), quirks are first matched by PCI SSID and then, if
there is no match, by codec SSID. The Lenovo "ThinkPad X1 Carbon 7th" has
an audio chip with PCI SSID 0x2292 and codec SSID 0x2293[1]. Therefore, fix
the quirk meant for that device to match on .subdevice == 0x2292.

2)
The "Thinkpad X1 Yoga 7th" does not exist. The companion product to the
Carbon 7th is the Yoga 4th. That device has an audio chip with PCI SSID
0x2292 and codec SSID 0x2292[2]. Given the behavior of
snd_hda_pick_fixup(), it is not possible to have a separate quirk for the
Yoga based on SSID. Therefore, merge the quirks meant for the Carbon and
Yoga. This preserves the current behavior for the Yoga.

I realize that we fairly recently raised it to 4.8, but the fact is, 4.9
is a much better minimum version to target.

We have a number of workarounds for actual bugs in pre-4.9 gcc versions
(including things like internal compiler errors on ARM), but we also
have some syntactic workarounds for lacking features.

In particular, raising the minimum to 4.9 means that we can now just
assume _Generic() exists, which is likely the much better replacement
for a lot of very convoluted built-time magic with conditionals on
sizeof and/or __builtin_choose_expr() with same_type() etc.

Using _Generic also means that you will need to have a very recent
version of 'sparse', but thats easy to build yourself, and much less of
a hassle than some old gcc version can be.

The latest (in a long string) of reasons for minimum compiler version
upgrades was commit 5435f73 ("efi/x86: Fix build with gcc 4").

Ard points out that RHEL 7 uses gcc-4.8, but the people who stay back on
old RHEL versions persumably also don't build their own kernels anyway.
And maybe they should cross-built or just have a little side affair with
a newer compiler?

When mod_delayed_work is called to modify the delay of pending work,
it might return false and queue a new work when pending work is
already scheduled or when try to grab pending work failed.

So, Increase the reference count when new work is scheduled to
avoid use-after-free.

The "auxtrace_info" and "auxtrace" functions are not set in "tool" member of
"annotate". As a result, perf annotate does not support parsing itrace data.

Before:

  # perf record -e arm_spe_0/branch_filter=1/ -a sleep 1
  [ perf record: Woken up 9 times to write data ]
  [ perf record: Captured and wrote 20.874 MB perf.data ]
  # perf annotate --stdio
  Error:
  The perf.data data has no samples!

Solution:

1. Add itrace options in help,
2. Set hook functions of "id_index", "auxtrace_info" and "auxtrace" in perf_tool.

After:

  # perf record --all-user -e arm_spe_0/branch_filter=1/ ls
  Couldn't synthesize bpf events.
  perf.data
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.010 MB perf.data ]

Commit

  3c73b81 ("x86/entry, selftests: Further improve user entry sanity checks")

added a warning if AC is set when in the kernel.

Commit

  662a022 ("x86/entry: Fix AC assertion")

changed the warning to only fire if the CPU supports SMAP.

However, the warning can still trigger on a machine that supports SMAP
but where it's disabled in the kernel config and when running the
syscall_nt selftest, for example:

  ------------[ cut here ]------------

  ...
  Call Trace:

   ? exc_general_protection

IS_ENABLED(CONFIG_X86_SMAP) could be added to the warning condition, but
even this would not be enough in case SMAP is disabled at boot time with
the "nosmap" parameter.

To be consistent with "nosmap" behaviour, clear X86_FEATURE_SMAP when
!CONFIG_X86_SMAP.

Found using entry-fuzz + satrandconfig.

====================
Several fixes to test_sockmap and added push/pop logic for msg_verify_data
Before the fixes, some of the tests in test_sockmap are problematic,
resulting in pseudo-correct result.

1. txmsg_pass is not set in some tests, as a result, no eBPF program is
attached to the sockmap.
2. In SENDPAGE, a wrong iov_length in test_send_large may result in some
test skippings and failures.
3. The calculation of total_bytes in msg_loop_rx is wrong, which may cause
msg_loop_rx end early and skip some data tests.

Besides, for msg_verify_data, I added push/pop checking logic to function
msg_verify_data and added more tests for different cases.

After that, I found that there are some bugs in bpf_msg_push_data,
bpf_msg_pop_data and sk_msg_reset_curr, and fix them. I guess the reason
why they have not been exposed is that because of the above problems, they
will not be triggered.

With the fixes, we can pass the sockmap test with data integrity test now.
However, the fixes to test_sockmap expose more problems in sockhash test
with SENDPAGE and ktls with SENDPAGE.

v1 -> v2:
  - Rebased to the latest bpf-next net branch.

The problem I observed,
1. In sockhash test, a NULL pointer kernel BUG will be reported for nearly
every cork test. More inspections are needed for splice_to_socket.

2. txmsg_pass are not set before, and some tests are skipped. Now after
the fixes, we have some failure cases now. More fixes are needed either
