>From the DS2408 datasheet [1]:
"Resume Command function checks the status of the RC flag and, if it is set,
directly transfers control to the control functions, similar to a Skip ROM
command. The only way to set the RC flag is through successfully executing
the Match ROM, Search ROM, Conditional Search ROM, or Overdrive-Match ROM
command"The function currently works perfectly fine in a multidrop bus, but when we
have only a single slave connected, then only a Skip ROM is used and Match
ROM is not called at all. This is leading to problems e.g. with single one
DS2408 connected, as the Resume Command is not working properly and the
device is responding with failing results after the Resume Command.This commit is fixing this by using a Skip ROM instead in those cases.
The bandwidth / performance advantage is exactly the same.Refs:

When we have success in 'Channel Access Write' but reading back latch
states fails, a write is retried without doing a proper slave reset.
This leads to protocol errors as the slave treats the next 'Channel
Access Write' as the continuation of previous command.This commit is fixing this by making sure if the retry loop re-runs, a
reset is performed, whatever the failure (CONFIRM_BYTE or the read
back).The loop was quite due for a cleanup and this change mandated it. By
isolating the CONFIG_W1_SLAVE_DS2408_READBACK case into it's own
function, we vastly reduce the visual and branching(runtime and
compile-time) noise.Reported-by: Mariusz Bialonczyk

The syzkaller USB fuzzer spotted a slab-out-of-bounds bug in the
ds2490 driver. This bug is caused by improper use of the altsetting
array in the usb_interface structure (the array's entries are not
always stored in numerical order), combined with a naive assumption
that all interfaces probed by the driver will have the expected number
of altsettings.The bug can be fixed by replacing references to the possibly
non-existent intf->altsetting[alt] entry with the guaranteed-to-exist
intf->cur_altsetting entry.Signed-off-by: Alan Stern

The Kconfig lexer supports special characters such as '.' and '/' in
the parameter context. In my understanding, the reason is just to
support bare file paths in the source statement.I do not see a good reason to complicate Kconfig for the room of
ambiguity.The majority of code already surrounds file paths with double quotes,
and it makes sense since file paths are constant string literals.Make it treewide consistent now.

This patch removes the w1 slave driver that used to register the w1 family
and instanciate a platform device at runtime. The code now lives in the
supply driver instead to avoid that level of indirection.The old device name "ds2760-battery.0" is preserved, so userspace
applications can access the same virtual device nodes as before.Note that because the w1 core does not currently have a framework for
suspend/resume, the driver now registers a PM notifier callback.Signed-off-by: Daniel Mack

The w1 master driver includes a complete open drain emulation
reimplementation among other things.This converts the driver and all board files using it to use
GPIO descriptors associated with the device to look up the
GPIO wire, as well ass the optional pull-up GPIO line.When probed from the device tree, the driver will just pick
descriptors and use them right off. For the two board files
in the kernel, we add descriptor lookups so we do not need
to keep any old platform data handling around for the GPIO
lines.As the platform data is also a state container for this driver,
we augment it to contain the GPIO descriptors.w1_gpio_write_bit_dir() and w1_gpio_write_bit_val() are gone
since this pair was a reimplementation of open drain emulation
which is now handled by gpiolib.The special "linux,open-drain" flag is a bit of mishap here:
it has the same semantic as the same flags in I2C: it means
that something in the platform is setting up the line as
open drain behind our back. We handle this the same way as
in I2C.To drive the pull-up, we need to bypass open drain emulation
in gpiolib for the line, and this is done by driving it high
using gpiod_set_raw_value() which has been augmented to have
the semantic of overriding the open drain emulation.We also augment the documentation to reflect the way to pass
GPIO descriptors from the machine.Acked-by: Evgeniy Polyakov

Many source files in the tree are missing licensing information, which
makes it harder for compliance tools to determine the correct license.By default all files without license information are under the default
license of the kernel, which is GPL version 2.Update the files which contain no license information with the 'GPL-2.0'
SPDX license identifier. The SPDX identifier is a legally binding
shorthand, which can be used instead of the full boiler plate text.This patch is based on work done by Thomas Gleixner and Kate Stewart and
Philippe Ombredanne.How this work was done:
Patches were generated and checked against linux-4.14-rc6 for a subset of
the use cases:
- file had no licensing information it it.
- file was a */uapi/* one with no licensing information in it,
- file was a */uapi/* one with existing licensing information,Further patches will be generated in subsequent months to fix up cases
where non-standard license headers were used, and references to license
had to be inferred by heuristics based on keywords.The analysis to determine which SPDX License Identifier to be applied to
a file was done in a spreadsheet of side by side results from of the
output of two independent scanners (ScanCode & Windriver) producing SPDX
tag:value files created by Philippe Ombredanne. Philippe prepared the
base worksheet, and did an initial spot review of a few 1000 files.The 4.13 kernel was the starting point of the analysis with 60,537 files
assessed. Kate Stewart did a file by file comparison of the scanner
results in the spreadsheet to determine which SPDX license identifier(s)
to be applied to the file. She confirmed any determination that was not
immediately clear with lawyers working with the Linux Foundation.Criteria used to select files for SPDX license identifier tagging was:
- Files considered eligible had to be source code files.
- Make and config files were included as candidates if they contained >5
lines of source
- File already had some variant of a license header in it (even if

This subpatch adds a driver for the DS28E17 Onewire to I2C master bridge.
Signed-off-by: Jan Kandziora

Signed-off-by: Greg Kroah-Hartman -
The w1_ds28e17 driver from the next part of this patch needs to emit
single-bit read timeslots to the DS28E17. The w1 subsystem already
has this function but it is not exported outside drivers/w1/w1_io.cThis subpatch exports the w1_touch_bit symbol with EXPORT_SYMBOL_GPL,
same as the other exported symbols in drivers/w1/w1_io.cMay be also useful later for writing drivers for other Onewire chips
which do single-bit communication.Signed-off-by: Jan Kandziora

The functions w1_ds2438_get_page, w1_ds2438_get_temperature,
w1_ds2438_change_config_bit and w1_ds2438_get_voltage are local to
the source and do not need to be in global scope, so make it static.Cleans up sparse warnings:
