In some error handling paths, an error code is assiegned to 'ret'.
However, the function always return 0.
Fix it and return the error code if such an error paths is taken.

The ACPI/machine-driver code refactoring introduced in 4.13 introduced
a regression for cases where we need a DMI-based quirk to select the
machine driver (the BIOS reports an invalid HID). The fix is just to
make sure the results of the quirk are actually used.
Fixes: 54746dabf770 ('ASoC: Improve machine driver selection based on quirk data')

I got the following kernel warning when loading snd-soc-skl module on
Dell Latitude 7270 laptop:
memremap attempted on mixed range 0x0000000000000000 size: 0x0
WARNING: CPU: 0 PID: 484 at kernel/memremap.c:98 memremap+0x8a/0x180
Call Trace:
skl_nhlt_init+0x82/0xf0 [snd_soc_skl]
skl_probe+0x2ee/0x7c0 [snd_soc_skl]
....
It seems that the machine doesn't support the SKL DSP gives the empty
NHLT entry, and it triggers the warning. For avoiding it, let do the
zero check before calling memremap().

During firmware and library download, sometimes it is observed that

Platform registration happens in probe work handler whereas machine
device is registered during skl_probe. This sometimes results in cpu
dais not found if the work handler is sufficiently delayed due to system
load, even with deferred probe of machine driver.
So move machine device registration after registering platform.

Sometimes during boot, panic is observed at sst_dsp_shim_read_unlocked().
This happens when interrupt occurs before the context is initialized. So

When NHLT endpoint is present for a SSP then we create clock for that SSP.
MCLK is consistent across endpoints and configuration for an SSP, so query
only for first endpoint for an SSP.
For SCLK/SCLKFS, the best fit is queried from the NHLT configurations which
matches the clock rate requested. Best fit is decided based on below:
1. If rate matches with multiple configurations, then the first
configuration is selected.
2. If for a selected fs and bits_per_sample, there are multiple endpoint
configuration match, then the configuration with max number of
channels is selected. So, the user has to set the rate which fits
max number of channels
So we create a platform device and pass clock information parsed as
platform data.

The Android 3.5mm Headset jack specification mentions that BTN_0 should
be mapped to KEY_MEDIA, but this is less logical than KEY_PLAYPAUSE,
which has much broader userspace support.
For example, the Chrome OS userspace now supports KEY_PLAYPAUSE to toggle
play/pause of videos and audio, but does not handle KEY_MEDIA.
Furthermore, Android itself now supports KEY_PLAYPAUSE equivalently, as the
new USB headset spec requires KEY_PLAYPAUSE for BTN_0.

"This series is predominantly bug-fixes, with a few small improvements
that have been outstanding over the last release cycle.
As usual, the associated bug-fixes have CC' tags for stable.
Also, things have been particularly quiet wrt new developments the
last months, with most folks continuing to focus on stability atop 4.x
stable kernels for their respective production configurations.
Also at this point, the stable trees have been synced up with
mainline. This will continue to be a priority, as production users
tend to run exclusively atop stable kernels, a few releases behind
mainline.

- Fix OOPs during removing TCMU device (Xiubo Li + Zhang Zhuoyu)
- Add netlink command reply supported option for each device (Kenjiro

afs_mkdir(), afs_create(), afs_link() and afs_symlink() all need to drop
the target dentry if a signal causes the operation to be killed immediately
before we try to contact the server.

Fix some of dentry handling in AFS directory ops:
(1) Do d_drop() on the new_dentry before assigning a new inode to it in
afs_vnode_new_inode(). It's fine to do this before calling afs_iget()
because the operation has taken place on the server.
(2) Replace d_instantiate()/d_rehash() with d_add().
(3) Don't d_drop() the new_dentry in afs_rename() on error.
Also fix afs_link() and afs_rename() to call key_put() on all error paths
where the key is taken.

Make afs_write_begin() wait for a page that's marked PG_writeback because:
(1) We need to avoid interference with the data being stored so that the
data on the server ends up in a defined state.
(2) page->private is used to track the window of dirty data within a page,
but it's also used by the storage code to track what's being written,
being cleared by the completion notification. Ownership can't be
relinquished by the storage code until completion because it a store
fails, the data must be remarked dirty.
Tracing shows something like the following (edited):
x86_64-linux-gn-15940 [1] afs_page_dirty: vn=ffff8800bef33800 9c75 begin 0-125
kworker/u8:3-114 [2] afs_page_dirty: vn=ffff8800bef33800 9c75 store+ 0-125

The clear (completion) corresponding to the store+ (store continuation from
a previous page) happens between the second begin (afs_write_begin) and the
store corresponding to that. This results in the second store not seeing
any data to write back, leading to the following warning:

The recent conversion of the task state recording to use task_state_index()
broke the sched_switch tracepoint task state output.
task_state_index() returns surprisingly an index (0-7) which is then
printed with __print_flags() applying bitmasks. Not really working and
resulting in weird states like 'prev_state=t' instead of 'prev_state=I'.
Use TASK_REPORT_MAX instead of TASK_STATE_MAX to report preemption. Build a
bitmask from the return value of task_state_index() and store it in
entry->prev_state, which makes __print_flags() work as expected.

The kbuild test robot reported this build warning:
Warning: arch/x86/tools/test_get_len found difference at <jump_table>:ffffffff8103dd2c
Warning: ffffffff8103dd82: f6 09 d8 testb $0xd8,(%rcx)
Warning: objdump says 3 bytes, but insn_get_length() says 2
Warning: decoded and checked 1569014 instructions with 1 warnings
This sequence seems to be a new instruction not in the opcode map in the Intel SDM.
The instruction sequence is "F6 09 d8", means Group3(F6), MOD(00)REG(001)RM(001), and 0xd8.
Intel SDM vol2 A.4 Table A-6 said the table index in the group is "Encoding of Bits 5,4,3 of
the ModR/M Byte (bits 2,1,0 in parenthesis)"
In that table, opcodes listed by the index REG bits as:
000 001 010 011 100 101 110 111
TEST Ib/Iz,(undefined),NOT,NEG,MUL AL/rAX,IMUL AL/rAX,DIV AL/rAX,IDIV AL/rAX
So, it seems TEST Ib is assigned to 001.
Add the new pattern.

Pull x86 platform driver fixes from Darren Hart:
"Fix two issues resulting from the dell-smbios refactoring and
introduction of the dell-smbios-wmi dispatcher.
The first ensures a proper error code is returned when kzalloc fails.
The second avoids an issue in older Dell BIOS implementations which
would fail if the more complex calls were made by limiting those
platforms to the simple calls such as those used by the existing
dell-laptop and dell-wmi drivers, preserving their functionality prior
to the addition of the dell-smbios-wmi dispatcher"
