4c9a3a6c9c parport: fix a kernel-doc markup
The kernel-doc markup inside share.c is actually for
__parport_register_driver. The actual goal seems to be
to document parport_register_driver().

So, fix the existing markup and add a new one.

a7f7f6248d treewide: replace '---help---' in Kconfig files with 'help'
Since commit 84af7a6194 ("checkpatch: kconfig: prefer 'help' over
'---help---'"), the number of '---help---' has been gradually
decreasing, but there are still more than 2400 instances.

This commit finishes the conversion. While I touched the lines,
I also fixed the indentation.

There are a variety of indentation styles found.

  a) 4 spaces + '---help---'
  b) 7 spaces + '---help---'
  c) 8 spaces + '---help---'
  d) 1 space + 1 tab + '---help---'
  e) 1 tab + '---help---'    (correct indentation)
  f) 1 tab + 1 space + '---help---'
  g) 1 tab + 2 spaces + '---help---'

In order to convert all of them to 1 tab + 'help', I ran the
following commend:

  $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/'

32927393dc sysctl: pass kernel pointers to ->proc_handler
Instead of having all the sysctl handlers deal with user pointers, which
is rather hairy in terms of the BPF interaction, copy the input to and
from  userspace in common code.  This also means that the strings are
always NUL-terminated by the common code, making the API a little bit
safer.

As most handler just pass through the data to one of the common handlers
a lot of the changes are mechnical.

231ec2f24d parport: load lowlevel driver if ports not found
Usually all the distro will load the parport low level driver as part
of their initialization. But we can get into a situation where all the
parallel port drivers are built as module and we unload all the modules
at a later time. Then if we just do "modprobe parport" it will only
load the parport module and will not load the low level driver which
will actually register the ports. So, check the bus if there is any
parport registered, if not, load the low level driver.

We can get into the above situation with all distro but only Suse has
setup the alias for "parport_lowlevel" and so it only works in Suse.
Users of Debian based distro will need to load the lowlevel module
manually.

 driver subsystem trees are ending up in here.  Now if that is good or

 	- coresight and intel_th hwtracing driver updates
 	- fpga driver updates
 	- extcon driver updates

cd238effef docs: kbuild: convert docs to ReST and rename to *.rst
The kbuild documentation clearly shows that the documents
there are written at different times: some use markdown,
some use their own peculiar logic to split sections.

Convert everything to ReST without affecting too much
the author's style and avoiding adding uneeded markups.

The conversion is actually:
  - add blank lines and identation in order to identify paragraphs;
  - fix tables markups;
  - add some lists markups;
  - mark literal blocks;
  - adjust title markups.

At its new index.rst, let's add a :orphan: while this is not linked to
the main index.rst file, in order to avoid build warnings.

1ce2c85137 Char/Misc driver fixes for 5.2-rc4
Here are some small char and misc driver fixes for 5.2-rc4 to resolve a
 number of reported issues.
 
 The most "notable" one here is the kernel headers in proc^Wsysfs fixes.
 Those changes move the header file info into sysfs and fixes the build
 issues that you reported.
 
 Other than that, a bunch of small habanalabs driver fixes, some fpga
 driver fixes, and a few other tiny driver fixes.
 
 All of these have been in linux-next for a while with no reported

b0a69f05b9 parport: ieee1284: mark expected switch fall-through
In preparation to enabling -Wimplicit-fallthrough, mark switch
cases where we are expecting to fall through.

This patch fixes the following warning:

drivers/parport/ieee1284.c: In function ‘parport_read’:
drivers/parport/ieee1284.c:722:6: warning: this statement may fall through [-Wimplicit-fallthrough=]
   if (parport_negotiate (port, IEEE1284_MODE_NIBBLE)) {
      ^
drivers/parport/ieee1284.c:726:2: note: here
  case IEEE1284_MODE_NIBBLE:
  ^~~~

Warning level 3 was used: -Wimplicit-fallthrough=3

Notice that, in this particular case, the code comment is modified
in accordance with what GCC is expecting to find.

This patch is part of the ongoing efforts to enable
-Wimplicit-fallthrough.

a3ac7917b7 Revert "parport: daisy: use new parport device model"
This reverts commit 1aec421120.

Steven Rostedt reports that it causes a hang at bootup and bisected it
to this commit.

The troigger is apparently a module alias for "parport_lowlevel" that
points to "parport_pc", which causes a hang with

    modprobe -q -- parport_lowlevel

blocking forever with a backtrace like this:

    wait_for_completion_killable+0x1c/0x28
    call_usermodehelper_exec+0xa7/0x108
    __request_module+0x351/0x3d8

    daisy_drv_init+0x31/0x4f [parport]

    do_init_module+0x50/0x1d4
    load_module+0x1c2e/0x21b3
    sys_init_module+0xef/0x117

Supid says:
 "Due to the new device model daisy driver will now try to find the
  parallel ports while trying to register its driver so that it can bind
  with them. Now, since daisy driver is loaded while parport bus is
  initialising the list of parport is still empty and it tries to load
  the lowlevel driver, which has an alias set to parport_pc, now causes
  a deadlock"

But I don't think the daisy driver should be loaded by the parport
initialization in the first place, so let's revert the whole change.

If the daisy driver can just initialize separately on its own (like a
driver should), instead of hooking into the parport init sequence
directly, this issue probably would go away.

21698fd579 parport_pc: fix find_superio io compare code, should use equal test.
In the original code before 181bf1e815 the loop was continuing until
it finds the first matching superios[i].io and p->base.
But after 181bf1e815 the logic changed and the loop now returns the
pointer to the first mismatched array element which is then used in
get_superio_dma() and get_superio_irq() and thus returning the wrong
value.
Fix the condition so that it now returns the correct pointer.

d5acba26bf Char/Misc driver patches for 4.19-rc1
Here is the bit set of char/misc drivers for 4.19-rc1
 
 There is a lot here, much more than normal, seems like everyone is
 writing new driver subsystems these days...  Anyway, major things here
 are:
 	- new FSI driver subsystem, yet-another-powerpc low-level
 	  hardware bus
 	- gnss, finally an in-kernel GPS subsystem to try to tame all of
 	  the crazy out-of-tree drivers that have been floating around
 	  for years, combined with some really hacky userspace
 	  implementations.  This is only for GNSS receivers, but you
 	  have to start somewhere, and this is great to see.
 Other than that, there are new slimbus drivers, new coresight drivers,
 new fpga drivers, and loads of DT bindings for all of these and existing
 drivers.
 
 Full details of everything is in the shortlog.
 
 All of these have been in linux-next for a while with no reported
 issues.

06dd3dfeea Char/Misc patches for 4.17-rc1
Here is the big set of char/misc driver patches for 4.17-rc1.
 
 There are a lot of little things in here, nothing huge, but all
 important to the different hardware types involved:
 	- thunderbolt driver updates
 	- parport updates (people still care...)
 	- nvmem driver updates
 	- mei updates (as always)
 	- hwtracing driver updates
 	- hyperv driver updates
 	- extcon driver updates
 	- and a handfull of even smaller driver subsystem and individual
 	  driver updates
 
 All of these have been in linux-next with no reported issues.

9abf8acea2 TTY/Serial driver patches for 4.17-rc1
Here is the big set of tty and serial driver patches for 4.17-rc1
 
 Not all that big really, most are just small fixes and additions to
 existing drivers.  There's a bunch of work on the imx serial driver
 recently for some reason, and a new embedded serial driver added as
 well.
 
 Full details are in the shortlog.
 
 All of these have been in the linux-next tree for a while with no
 reported issues.
