I2C clients may misunderstand recovery pulses if they can't read SDA to
bail out early. In the worst case, as a write operation. To avoid that
and if we can write SDA, try to send STOP to avoid the
misinterpretation.

In 2016 GNU Make made a backwards incompatible change to the way '#'
characters were handled in Makefiles when used inside functions or
macros:
http://git.savannah.gnu.org/cgit/make.git/commit/?id=c6966b323811c37acedff05b57
Due to this change, when attempting to run `make prepare' I get a
spurious make syntax error:
/home/earnest/linux/tools/objtool/.fixdep.o.cmd:1: *** missing separator. Stop.
When inspecting `.fixdep.o.cmd' it includes two lines which use
unescaped comment characters at the top:
\# cannot find fixdep (/home/earnest/linux/tools/objtool//fixdep)
\# using basic dep data
This is because `tools/build/Build.include' prints these '\#'
characters:
printf '\# cannot find fixdep (%s)\n' $(fixdep) > $(dot-target).cmd; \
printf '\# using basic dep data\n\n' >> $(dot-target).cmd; \
This completes commit 9564a8cf42 ("Kbuild: fix # escaping in .cmd files

In the error path of fsi_master_register(), we currently

to the structure to be dropped, thus freeing the enclosing
structure, which isn't what the callers want.
Use device_del() instead so that we return to the caller
with a refcount of 1. The caller can then assume that it
must use put_device() after a call to fsi_master_register()
regardless of whether the latter suceeded or failed.

Those values control the amount of "dummy" clocks between commands and

This adds a way to configure them from sysfs (to be later extended to

Dynamic ftrace requires modifying the code segments that are usually
set to read-only. To do this, a per arch function is called both before
and after the ftrace modifications are performed. The "before" function
will set kernel code text to read-write to allow for ftrace to make the
modifications, and the "after" function will set the kernel code text
back to "read-only" to keep the kernel code text protected.
The issue happens when dynamic ftrace is tested at boot up. The test is
done before the kernel code text has been set to read-only. But the
"before" and "after" calls are still performed. The "after" call will
change the kernel code text to read-only prematurely, and other boot
code that expects this code to be read-write will fail.
The solution is to add a variable that is set when the kernel code text
is expected to be converted to read-only, and make the ftrace "before"
and "after" calls do nothing if that variable is not yet set. This is
similar to the x86 solution from commit 1623963097 ("ftrace, x86:
make kernel text writable only for conversions").

Here are two tiny staging driver fixes for reported issues for 4.18-rc5.
One fixes the r8822be driver to properly work on lots of new laptops,
the other is for the rtl8723bs driver to fix an underflow error.
Both have been in linux-next for a while with no reported issues.

Here are a number of small USB fixes for 4.18-rc5.
Nothing major here, just the normal set of new device ids, xhci fixes,
and some typec fixes. The typec fix required some tiny changes in an
i2c driver, which that maintainer acked to come through my tree.
All of these have been in linux-next for a while with no reported

state during the 4.17 cycle which caused some systems to power up
immediately after they had been turned off.
